Windows Firewall is blocking access to computers on my home network

Q: Windows Firewall is blocking access to computers on my home network


I have in my house a small network consisting of two computers, a Desktop and a Laptop. The desktop is connected directly to a Cable modem. I also have a Wireless-G access point connected to the modem, and through this i can connect my laptop to the Internet.

I have both computers setup in a workgroup, sharing files between them.

Both computers are running Windows XP Home with service pack 2. As far as i can see the Firewall configurations are the same in both computers. I have enabled the UPnP framework and it worked fine for a while. However when i turned off both computers for the first time after setting up the network, and turned them back on, the Firewall on the desktop began blocking the laptop, so it couldnt recognize it as part of the workgroup, thus the network stopped working.

From the desktop i can access the laptop without any problems. However, from the laptop i cant access the desktop. I get a message saying:

"An error occurred while reconnecting to W: to (mapped drive from desktop name) Microsoft Windows Network: The local device name is already in use. This connection has not been restored"
If I turn off the firewall the network connections work perfectly, however i can't seem to get it to work with the firewall and i really don't like the idea of having the firewall turned off.

I really don't know what to try next, so I would appreciate it very much if someone could help me out with this.

Thank you

Preferred Solution: Windows Firewall is blocking access to computers on my home network

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hi All.
I’m having problems remotely accessing the C and D $ of our Windows 7 boxes over the network. I know the firewall is blocking this access because I can access it if the firewall is disabled but I can’t for the life
of me figure out which setting I need to change in the firewall console to all access to the drives.

None of the drives are shared so we always access by going \\PCNAME\c$ or d$
I would very much appreciate assistance with this as I’ve completely run out of ideas.

If you are entirely sure it's the firewall, open UDP and TCP ports 135 through 139.

Over the past week I've had Comodo Firewall blocking network access to a couple of Windows services and I can't understand why. On Monday it went and blocked three svchost.exe inbound connections, on Wednesday it blocked a MSASCui.exe inbound request (Windows Defender. It keeps turning itself on even though I disabled multiple times a week) and within the last hour I've had it block a outbound request from "Windows Operating System". I've unblocked all of them.

Any reason for this? System applications, files and processes should be trusted by Comodo so I can't understand the reason why the firewall is blocking network access to them. I also haven't a clue what svchost would be receiving with its inbound requests or what Windows Operating System would be sending with its outbound request.

I'm using Windows 7 if that's any help. I'm off to work but shall respond to any questions or queries once I return.

I have 4 computers on my home network, 3 of which are running Windows 7 pro, and the other one is Windows Vista home. All of the computers are in the same workgroup (I tried using homegroup as well, but it worked terribly and I disabled it), all of them have the same network settings (file and printer sharing: on, network discovery: on, etc), all of them have access to the internet, and for the purposes of troubleshooting, I have disable all AV software and firewalls.

For months I was able to connect to all of my computers from any other computer. Suddenly, my main office computer (Windows 7, which I'm also using as a Quickbooks file server, so I NEED it to work!) started losing it's connection and file sharing with the others. I would restart it, and that would fix the problem for anywhere from 1 minute, to 1 week. Now, I simply cannot connect to it at all, with any computers, and rebooting doesn't help.

The problem-computer is usually visible in the network window of the other computers, but trying to access it returns an error of 0x80070035 (cannot access, check the spelling, blah blah).

Hi, I have a desktop and a laptop setup at home, I have recently upgraded both to Windows 10. Both were previously running Windows 7 Home Premium and could identify each other on the network and I could access files on either PC from one or the other at any time.

With the upgrade to Windows 10 I am still able to see the other machine on the local network, but I am unable to access their folders and move files between machines. The error message I get is as follows:

When I run the network diagnosis no errors are detected and it asks me if I want to explore other options.

The full error message is:

I do have shared libraries available across both machines that are part of my homegroup, so I can access the video files in the hard drive of my desktop from my Laptop but only to play them - not to move them around.

I suspect this is either a user validation issue, or a firewall issue and I'm not sure how to go about checking whether this is the case or not.

Any assistance much appreciated.

Firstly as a new member let me say hi and thank you for allowing me to use this community.

Additionally let me apologise if this post is technically in the incorrect sub. It was a toss up between networking and the security sections but since it deals with my internal network rather than connections beyond my network or to the internet I thought it was more relevant to networking.

I recently upgraded to Windows 7 and the process for adding some of my older hardware has been an interesting one. The one that has got me stuck is being able to access my network scanners shared 'mailboxes' in order to retrieve my scans.

The product in question is a Xerox 6204 wide format printer/scanner. The installation process for the basic print server to run the 6204 as a network printer went fairly smoothly and appears to be working as expected. However the problem arises when I want to use the 6204's scan functionality. Scans are stored in 'mailboxes' on the 6204 and must be retrieved by a piece of software by Xerox called 'Wide Format Scan Service'. This program basically connects to the mailboxes via the IP address of the 6204 on the network and from there should allow me to download the scans to my Windows 7 machine. Unfortunately, in order to be able to connect to the mailboxes I am currently having to disable the Windows 7 firewall entirely.

I have tried adding the Wide Format Scan Service to the list of allowed programs which yields an 'Unable to connect to 6204' error. I have atte... Read more

Hi guys,

Hope someone can help me on this. I've got two computers, one with Windows 7 Home Pro and a new computer with Windows 7 Ultimate.
I'm trying to set up a network so that I can access everything on both computers. The newer computer with Ultimate on it has a SSD drive for my operating system and programs and an internal drive for storage. I need to be able to access the storage drive with the computer with Home Pro on it. Right now the only thing I can access is my public folder on the main drive. The storage drive (e) is showing up in the network but when I click on it I get a message that I do not have perimssion to view it. I've tried every suggestion that I can find on how to fix this nothing works.
On the older computer with Home Pro on it I'm getting a "There is a second homegroup on this computer would you like to join it?" message. I can't figure out how it got there, how to view it, how to delete it, or even how to join it as all passwords I have do not work.

Let me know if you need any other information. I have screen shots if needed.



A:How to set up home network to access everything on computers

Hello to a Buckeye Gal,

Chev65 is probably one of our most knowledgable members on networking.

I don't use "homegroups" because I have differenet versions of Windows running on my networks. (98, XP, Vista, Win7). I always use business type networks. You have to make sure you get the sharing right on each HD & folders that you want shared on the network.

This is a similar problem to one I saw elsewhere on here.
I have three computers on my Home Network - mine, my wife's and a spare that we have. All are running XP Pro SP2 (fully updated).
My router is a NetComm 1300Plus4.
Until recently all was fine. However, now I can read both the other computers from my own, but get a message telling me that I may not have permission to access my own from either of the others - Access is denied!
Thus far, I have run the Wizard and created a Network Setup Disk and that hasn't worked. I have run the Wizard individually on each of the three machines and that hasn't worked. I have checked the Firewall settings on all three and they are the same.
Any ideas at all, because I am now totally at a loss!

I have a wired network consisting of 3 Windows 7 Profesional computers and one WHS server. My network configuration has been in place for over 2-years without an issue. One of my Windows 7 computers has developed an issue where I can no longer access the the other two Windows 7 computers through Windows Exployer. When you go into the control panel and Networking and the Advanced network sharing and file sharing button are off, when I attempt to turn them on it does not let me turn them on (with Adminstrator privileges of course), keeps returning to the disabled position. If I disable the Windows firewall everything works, no problems.

I have ran the troubleshooting for network sharing and it ends up with the the Windows Firewall settings as incorrect, however the troubleshooter attempt to fix fails..

I am running Microsoft Security Essentials and also use Malwarebytes for virus and malware security. I have ran both these on full scans without an issue.

Any suggestion would be appreciated.

Unable to see home network computers in Windows Explorer Network screen.

I have a home network with 2 laptops and 1 desktop. The desktop I use as a "file server" in that all work done on the laptops is stored to the desktop. The desktop computer name is HAL. One laptop is fine and sees the network. The other just stopped seeing it; rebooted the laptop; rebooted HAL; did a number of refreshes without any luck. I opened EXCEL and found a worksheet that was listed that I knew was saved on HAL. Was able to open the file and when I tried the SAVE AS I could navigate through all of HAL just as normal. Went to Windows Explorer and still no HAL listed as a COMPUTER on the NETWORK. I have a internet connection so I know I am making it to the router at least. And when I check NETWORK AND SHARING CENTER it shows an active home network. The laptop is running Windows 7 Home Premium Service Pack 1 Build 7601. Thanks in advance for any help! George

I recently upgraded the 3 machines on my home network to windows 10 home. I am having frustrating issues with the network at the moment and would appreciate any help available.

Currently when I open up "this PC" and click on network, only one of the 3 computers shows up, and this machine is not the local machine on 2 of them. However If I type in the UNC address for the other machines I can access them.

If I set up a home group all the computers show up in the home group roll out under "this PC" but still not in the network.

Something else that is strange. If I look at "network and sharing center" two of the the computer see one private network name and the other one sees a different name.

I did not have any of these issues with windows 7 prior to upgrade. The exact same hardware (PC's, router, ect.) functioned correctly. all of the PC's are hard wired to the router so any WiFi issues can be ruled out.

Thank you in advance for your help!

A:Computers in network not showing up correctly Windows 10 Home.

This gets so time consuming, that I hate to even get started but I have a similar problem. I actually think that some update to win 10 caused this issue but can't verify it. I have 2 desktops and 2 laptops on the network. One desktop and one notebook were upgraded to win 10 about a month ago. Everything was fine then. Since three days ago, the notebook does not show up on the other computers at all including itself. This is under "network" on file explorer. On the notebook under HOMEGROUP , it shows a mixture of username and computer names but never the same thing twice. The WIn 10 desktop shows the same mixture under Homegroup, but shows everything under NETWORK but the notebook. The note book has become the hidden device on all four computers in the house. The frustrating things is that tomorrow, these results will all be different. So far the required shared folders and printers work as advertised, even though the names don't show up !!!!

Hi folks.

Long time since I posted on here last!

I have recently bought a laptop, and have popped a NIC into the desktop, connected with a crossover cable, and can now share the ADSL connection.

One problem I am having - Norton Firewall 2005 is getting in my way!

Although the ADSL sharing works like a dream, I can't access the shared folders / printer on either machine (Norton blocks the traffic, and connection times-out).

If I disable Norton, it works fine, so I am assuming I need to configure Norton to allow the laptop / desktop to speak to each other.

I am totally new to networking, so I would appreciate any help or suggestions.

Windows 10 laptop cannot access network computers

Network setup: W10 laptop(Home, v1607 but problem was even before v1511) connected via either Ethernet or wireless to a TP-link MR3420 router( firewall disabled). W10 tablet (Pro, v1511), wireless. W7 desktop Ethernet connected. Internet is provided via a separate LTE router connected to the TP-link. Buffalo NAS LS220 connected via cable to TP-link.

Problem: cannot access other computers or NAS on my home network from my w10 laptop (\\COMPUTERNAME or \\IP-address makes no difference). Also, The laptop itself cant be accessed from other computers. Other computers can see the laptop but generate 0x70080035 (windows cannot access...) when I click on the laptop. The same happens when trying to access other computes from the laptop. The laptop can see the tablet but not the W7 desktop. If I enable/disable SMB1 in the NAS, or create a new folder in the NAS, I can sometimes get the NAS visible from the laptop until next reboot, however I can never browse the shared folders. This was possible from the laptop a few weeks ago before the problems started. There has never been any problem to access the webGUI:s for the router or NAS from the laptop. The tablet, W7desktop & NAS has no problem accessing each others folders.

I have spent many days on this and lost track of all suggested fixes & registry hacks that I have tried without success, but below is a list of some things tested:

What did you change them to? Usually, unless an ISP otherwise specifies, the first item should be checked about "Automatically detect......" and nothing else. I've found if the Proxy section has checkmarks, and the ISP doesn't require them, that infections can cause that and can prevent opening Web sites.

Sounds like it is using some kind of network address translation that the other ends FTP doesn't accept. Look at the log on your FTP client for a clue as to why it's not connecting. Don't use IE for an FTP client because it has no log you can read. Use something like WS_FTP

Running Windows XP Home Service Pack 2

It seems that what I'm trying to do should be simple. Yet I've literally been trying to do it for over a year. I stumbled upon this forum, so maybe you can make my dreams come true and actually give me a shared network *angels singing*.

Keep in mind, I once had a shared network and everything was fine. Then one day, it mysteriously stopped, and hasn't run since, even after hundreds (literally) of attempts to set it up again.

For the moment, all I want to do is have my computer (we'll call this computer, "Sony Laptop") appear in its own "My Network Places" window - not concerned with the other networked computer at the moment. I have tried "Set up a home or small office network" and "set up a wireless network for a home or small office" dozens of times, chosen every single combination possible, completed them, restarted, but "Sony Laptop" still never appears in "My Network Places." I cannot for the life of me understand it.

You need to look at the dependency list for each service. In the case of Computer Browser, it's Workstation and Server.

Since Workstation is failing, that's probably the place to start.

Do you have WKSSVC.DLL in C:\Windows\system32? That's the workstation service, and it appears to be the missing module. I'd first try copying that from the installation disk, if it's missing, and then register it too by:

Start, Run, regsvr32 wkssvc.dll

If you can't find the DLL, you can run sfc /scannow to restore missing files.

A shortcut may be to download the file from DLL Dump and register it as described above.

Hey guys, I recently just added the new ZoneAlarm firewall to my computer and apparently its denied anyone in our house access to my part of the network (we use linksys wireless). I've tried to mess with certain options on the firewall but i really have no clue what im doing. I just wanted to know if anyone had any ideas or experience in dealing with firewalls and networks and possibly this problem. Thanks for your time.


A:Firewall blocking network sharing?

Yes, your firewall is very likely stopping your machine from sharing.

Usually when you first install zonealarm, it will start telling you what is trying to get through and whether you want to block it or accept it.

Reset the firewall, and accept it when your other PCs are trying to access.


Find out the IP addresss of the PCs you want to give access to, and grant them access by adding them into your zonealarm configuration.


Someone with more zone-alarm experience should be able to tell you the actual clicks to do this.

I ~started to think that the USB Reciever Device was damged or something, but it was quite impossible since i hadnt touch it since the other day and it had worked properly, after many thoughts, i asked myself: what if my firewall is blocking the USB Reciever´s software??? so i went to COMODO´s Logs and saw various reports of Network Violation or something, and said tht My IP was blocked. Then i was like: OMG! I should have known it was this!

So yeh, i uninstalled comodo, and then it worked so im here posting a help thread lol.

In other words: Can anyone tell me a way for comodo not to block my access to the internet ( wich is done by the USB Software wich probably got blocked )

So what? I mean i really want comodo´s protection Should i like, set the USB Utility software as an allowed application or something?

I've been using Norton Personal Firewall (as part of Norton Internet Security 2005) for over a year now without any problems. But today when I tried to access the internet as usual I couldn't connect.

After trying all sorts of things I realised that it was the Norton Firewall that was stopping me from connecting to the net, and now I have to disable it in order to use the internet.

I hadn't been messing with the settings or anything like that.
Does anyone know why this might have happened?

Recently, my Windows Vista desktop computer became infected. I ran Malwarebytes, which found some trojans, but I still could not get an Internet connection on the desktop. My wireless network, however, was working, so we could get online with a laptop and Ipad. But when I try to go online from the desktop, I get "server not found" errors. This happened with Firefox, IE, and Safari. When I ping sites like Yahoo.com, I get no response.

I called my ISP, and they had me do various tests (such as ipconfig /renew and ipconfig /release), and in the end determined that it was the McAfee firewall. When I turned it off, I could get a connection again. When I turned it back on, I had the same problems.

I don't want to surf the web without a firewall. How can I solve the underlying problem?

Thank you for any assistance.

When the server's windows firewall is turned on, it does not let us open a program and access a file that is on the server. But, when the firewall is turned off - there are no issues. Is there a way around this without having to keep the firewall turned off?

It's an Windows SBS server

A:How do you stop a firewall from blocking your access to a server?

With a desktop Windows system you'd have to enable file sharing and specify what folders/files can be shared. There are also ways to configure the firewall (Control Panel - Windows Firewall) to open ports or allow specified programs access. I suspect Windows server is somewhat similar.

Not sure how actively anyone is tracking user needs here, but figured I had nothing to lose by asking for help...unable to find an understandable answer here so far.
I had been happily running Virtual PC 2007 on a Win 7 Home system, printing on a network physically connected via usb cable to a Win XP system.  I have now replaced the XP tower with a Windows 10 tower, with that printer attached to that tower, and
functioning normally.
When I run Virtual PC 2007 on the Win 7 system, it "sees" the Win 10 system, but on trying to install the printer, it is asking for a password to the Win 10 system.
I am guessing that it would require a ton of tweaks to get around this, and although I am not a full blown novice, I never like fiddling with too many settings that might screw up everything else that is working.
So, long story short, is there in fact a reasonably simple way to work around this, or should I just give up to progress and new operating systems?
Thanks to anyone who might be willing to point me in the right direction.

I have an MS Access Database 2010 running on SQL 2008 R2; front end is Access 2010, It is configured to allow remote Runtime users to access it.

I have Firewall exceptions set up for TCP port 1433 and UDP port 1434. I also have an exception for file sharing.

When trying to log into my database using runtime from remote computers I get this error:

Connetion Failed:

Connetion Failed:

If I turn the firewall off I can access the database remotely using Runtime with no problems.

Here is the firewall log:

All of a sudden my Windows XP Home Addition Gateway Laptop is having connection problems to the internet, using my Cablevision of Long Island service. They say service to my modem is good and diagnostics show the connection is being "firewalled". I have only one known firewal, a Windows firewall and when I turn it off, they still show the connection firewalled.I used Network Repair suggested by windows. It printed a log showing problems corrected. Next time I used computer, the same problem occurred. In particular, the problem makes it impossible to get into Google Chrome, which is the browser I like to use. Windows Explorer will open, but then freeze.Someone suggested to me that updates by either Symentec(Norton) or by Windows itself has created this problem.How do I correct this?

I did not set up my pc's to share over my home wireless network, but suddenly today I see that all drives and the printer are available between each computer. I had tried to set up the computers to share months ago, but never got it to work and gave up.

The desktop is old, running WinME, one laptop is running WinXPpro, the other laptop is running Vista. They are all connected to a Westell router/dsl modem for internet through Verizon.

So, I turn the desktop off daily. Today I go to turn it off and it says the WinXP laptop is connected and do I really want to shut down. I go to windows explorer on both machines and sure enough I have access to the other drives on each computer. I start the Vista machine and see the same.

Am I compromised?

A:MY home computers suddenly sharing over home wireless network

If you didn't make the change to share all drives, then somebody did. I would assume the worst. Time to reformat and reinstall.

Windows ME is past end of life, and no security updates are provided by MS. I wouldn't run it anymore. Maybe you'd want to try out some linux distros, some are quite good on old hardware. See this review:

It seems you don't have a separate router, I would advise you to get one. I have a modem/router too but I also have a separate hardware firewall/router. The modem/router does NAT but I constantly see connections/attacks making it past the modem/router to my firewall. Having a separate router is a good thing.

Since you are using wireless, did you enable the encryption? If you have WPA or WPA2 use them and setup a long and complicated passphrase. Use WEP if you have no other choice cause WEP can be broken into real quick. You must enable encryption because with wireless, all your machines are sitting ducks when you have close range attackers, whereas with wired, at least you still have a perimeter which you can fortify with a firewall. Also it is especially important to have software firewalls on Each PC when using wireless.

Hey everyone,
This is my first post, and first time I've not been able to solve my problem by searching previous posts...so hopefully someone can help me out.
I'm trying to install a downloaded .exe file, and Windows firewall is blocking it regardless of whether the firewall is active or not; the specific error message & the subsequent Windows help screen are attached. The Windows help screen indicates that the file came from an "untrusted" website, and suggests adding the source website to the "trusted" list if I'm sure that the file is safe (which I am, and I did...and I'm getting the same results when I try to open the .exe).
After the adding the source site to the "trusted" category failed, I attempted to run the file after completely shutting off Windows firewall (along with Bitdefender, which I'm also running). I'm still getting the same error message; it's as if Windows firewall is just ignoring me...can anyone help me either get around this, or tell me how to really shut off the firewall so it stops blocking this file?

A:Windows firewall blocking .exe file even after firewall is disabled

Welcome to the Seven Forums.

You can turn the Windows Firewall back on. The issue has nothing to do with the Firewall.

You can turn the Bitdefender back on too.

The issue is probably caused by one or more settings within IE. You might try resetting IE:
Internet Explorer - Reset

My laptop shows no errors in device manager and i have used numerous cmd commands that have found zero issues with my laptop and also the windows firewall fixit program that was listed in the forums but still no internet access and no firewall.

I recently purchased an HP desktop with Windows 7. I also own a desktop with Windows XP and a laptop with Vista. I networked the Windows 7 to the existing network ?workgroup?. Then I following instructions from this website:
When I went into the folders on the Windows 7 in order to set share setting, the button entitled ?share? was grayed out. I can view the Windows folders from both the Windows XP and Vista computers, but when I try to access the folders from the Windows 7 computer it says the following:
?Windows cannot access \\WAYNE ? Check the spelling of the name. Otherwise, there might be a problem with your network. To try to identify and resolve network problems, click diagnose.?
I even followed this advice by changing the registry files:
1. Open the Start Menu.
2. In the white line (Start Search) area, type regedit and press Enter.
3. Click Continue for UAC prompt.
4. In regedit, go to: -HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Lsa
5. In the right pane, right click LmCompatibilityLevel and click Modify.
NOTE: If it doesn?t already exist, create a DWORD value named
6. Set the value to 1
7. Reboot

Nothing worked, I?m assuming it?s a firewall problem. How can I fix it?
Thanks for your help!

Hoping someone can help my frustration with my home wireless.
I have a new laptop that cannot access my home wireless. There are 3 other computers that can access it so I know it's working. When I work away the new laptop can access other wireless connections. But as soon as I get home it's stuck on 'acquiring network address'.
The weird thing is my kindle does the same thing as does my friends iphones & ipads. They all connect wireless no problems elsewhere but cannot at my house.

I've tried switching off the other others computers connections & trying to connect.
Resetting the router

Please help getting very frustrated, not sure if it's my laptop or the router!??!?!

Thanks in advance guys!

A:Laptop cannot access home wireless, can access elsewhere & other computers are on it

What you describe can be caused by using the wrong network key. To check this go to the routers wireless settings, and in the Security Options, click Disable. If you are then able to connect it is down to the network key.

You might also want to try changing the channel and Mode in the router. Change the Mode to 'g only' and the channel to No 13. Work your way down from there until you get the best result.

Hey, Is there a way of accessing a Windows Home Network without being on that network. I have some huge files (4 GB +) (Ripped DVD's) that I stream using XBMC and I was wondering if there was a way...

By Accessing it I mean connecting to it using another Computer (Probably Windows) that is NOT on the same Network...

Prior to installing SP2 whenever I wanted to communicate with my desktop computer on a LAN I would just click on Network in Windows Explorer and both my laptop and desktop would appear. Since the install of SP2 I now get:
- Entire Network which when clicked on gives:
- Microsoft Terminal Services
- Microsoft Windows Network which when clicked on gives:
- Workgroup which when clicked on gives:
My Laptop (only)
- Netware or Compatible Network
- Web Client Network

If I go to Start > Search > Find People and then enter my My Desktop it does find the computer...eventually!

Why can't I access it from Explorer anymore and what do I need to do to get the local network to appear as it used to please?

I have 2 Windows Home Premium 7 systems that cannot access each other on my home network which also has 2 XP pro systems on it. I get the Windows Cannot Access, you don't have permissions error.

I tried the following to fix this:

Assured that all systems are in WORKGROUP because of the XPS on the system

Turned on network discovery
Turned on file and printer sharing
Turned on read/write file sharing
Turned off password protection
Allowed Windows to manage homegroup connections

Rebooted and checked file access, etc. but no success. Now one of the Windows 7 systems can see and access both XPs on the system, and the other Window 7 systems can only see and access one of the XPs, it cannot see the second XP. Right now I am mostly interested in just getting the 2 Window 7 systems to access and share data. What else to try?

A:Windows 7 systems cannot access each other on a home network

Just curious, but what are you trying to share?
