Solved: Getting IP addr from DHCP but cannot ping DHCP server

Q: Solved: Getting IP addr from DHCP but cannot ping DHCP server

I'm running a simple network at home with a Linksys BEFSR41 router. I have two computers hooked up wired and a wireless router acting like an access point that I use for my laptop occasionally. Until this weekend I've been having no problems but I shut down the computers due to weather and now one of them is not able to communicate with any others on the network. The problem computer will get an address supplied to it by the router (DHCP server) but once it has it I cannot get any other connectivity. Of course this is hindering internet access on this computer. I can ping the loopback and assigned IP addresses w/o problems but when I ping the default gateway (router) and/or the other computer I get "Request timed out." I initially thought it was the NIC so I bought another one but still get the same issue. I've moved the cards to different PCI slots but no luck. I tested the cable running from the computer and the router but found no problems. I even tried resetting the TCP/IP stack but still didn't work. The computer in question is running WinXP SP2 with the original NIC being a Linksys LNE100TX and the new one being a D-Link DFE-530TX+.

Any clues on this? If more info is needed let me know--it's been a while since I've posted. Thanks in advance.

My WinXP Home PC won't connect properly (limited connectivity/no internet) via ethernet cable to my router (Belkin N150).

Ipconfig /all shows the IP address as 169.254.117.71 but this is determined by an entry in the registry at HLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{39A...} > 'DhcpIPAddress' - REG_SZ - 169.254.117.71. Also listed at 'IPAutoconfigurationAddress'. My laptop connects fine plugged into the same port getting it's IP automatically (192.168.2.2) and getting internet fine.

After much searching I can't figure out what's wrong.

I've tried adding a DWORD entry 'IPAutoconfigurationEnabled' = 0, also tried deleting the 2 values.
Tried setting the IP manually to 192.168.2.6 - limited connectivity goes away but I get no internet connection from the router nor file sharing.

Any help please?

Hey,

So I'm somewhat of an idiot when it comes to computers, and I'm having quite a hard time here.

I currently have 3 laptops running on a D-Link DIR-615 wireless router.

2 of them are running fine, but the 3rd one can't connect to the Internet. Well, sometimes it will for a few seconds, but most of the time, it will time out, and Internet's always dropped.

When I ran a Intel PROset/Wireless Manual Diagnostic, all the test pass except for the Ping Test. Sometimes, it will say "Response: Default Gateway, No Response: DHCP server", although most of the times, both have no response.

Here's the interesting thing: I have the laptop for about 6 weeks now. At the beginning, it worked perfectly well. After 4 weeks, Internet kept crashing. Did a system restore, and Internet worked for a few days ...then, out of the blue, started crashing again, and now I can't connect ever (even though I always show a strong signal reception on my icon).

I have no idea what to do here. I've been going through forums, tried the following:

- Changing wireless channel
- TCP/IP stack repair options
- Calling Dell (what a joke that was...)

I just don't understand why one laptop doesn't connect (even though it did 3 weeks ago without problem) and the 2 other ones work great ...my roomates are getting tired of me borrowing their laptops, so I need to figure this out!
PLEASE HELP !!!

Thanks !!

Is yours farther from the router than the others? Have you installed the newest driver for the wireless adaptor?

Lets take a peek at your network environment:

First:

Power Cycle everything . . Turn off the Modem, router and all pc's . . turn on the Modem and wait a few minutes for the lights to stabilize . . then turn on the router, then one pc at a time. See if you connect to the internet.

Then:

Remove all the stored wireless network profiles and search for the network again.

How to Remove Stored Wireless Network Profiles for XP, Vista, and Windows 7

Then: check your browser's settings, remove any proxy settings if found here's how.

Then:

with the pc connected to the router, Click on Start . . Run . . type CMD

At the > prompt type type the following command: IPCONFIG /ALL


Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

QUESTION #1:
Is it better to use Win2000 Server DHCP or DHCP from my Netgear wireless router?

#1 BACKGROUND:
I am currently in the process of setting up a Win2000 server on my home network which consists of four other 2000/XP machines.
The server is going to be configured as a domain controller and will utilize the Active Directory.

Should I use the Win2000 Server DHCP or stick with my wireless router as the DHCP server? What are the advantages/disadvantages to both and which would be easier to maintain.

QUESTION #2
Is a 550mhz PIII with 256MB RAM fast enough to make a good home server running Win2000 server?

BACKGROUND #2
The server is going to have (2) 120GB Western Digital 7200rpm drives with 8MB cache for storage and a single 60GB Western Digital 7200rpm drive for the OS and few other applications.

The server's primary function is to serve as a media server with an approaching 10GB of MP3 and music video files which is continually going to grow. Disk contention is at a minimum since there are only four PC's on the network. There will also be a lot of digital photos stored on the server and will also serve as a place to perform backups from the other four networked PC's.
 

A:Win2000 Server DHCP or Router DHCP?

We have a similar setup in our office using Small Business Server, a public IP coming into our router with DHCP turned on, connected to a NIC in the internal DHCP server (which is also running ISA). A second NIC in the server bridges to the internal hub to provide DHCP services to the clients. This way we control port filtering in 2 places and with 2 levels of NAT taking place we feel secure. It may be overkill but we're concerned that EVERYONE is trying to hack into ISA and DHCP servers connected directly to public IP that this setup provides an added level of security.

Hello, the ping test is entirely useless if you are not actually connected to the network Please describe your issue in more details, including any messages or errors that you receive when you try to connect to your wireless router; what kind of wireless security is on the router, what make and model, if you are able to connect any other computers or devices to it...you get the point.

Hey,

Before continuing, this is a thread that I currently have going, if you want extra details on what's been going on. I'll try to explain it quickly here:

My laptop won't connect to wireless Internet. Doesn't matter where I am, so it's not a router problem.
I've tried many things (can be seen on the other thread), and still can't get wireless Internet connection.

Before I go any further, I'm not great with computers, so any instructions, please, eaassyyy!

Now the weird thing is, when I'm in Safe Mode with networking, Internet seems to be working fine!
As you can see in the title, my Ping test is showing something is wrong.

I have no idea what to do here. I've been going through forums, tried the following:

- Changing wireless channel
- TCP/IP stack repair options
- Calling Dell (what a joke that was...)
- ran an ipconfig /all (see on the other thread through my forum link)
- removed Mcafee (using Windows Essentials), and when I did that, Internet worked for 5-10mins then crashed again.
- checked the Mac filtering settings on my router settings

Also, my computer crashed the other day (got a blue screen, shut itself down). I posted the details in the thread.

Okay, I got a new client a few weeks ago. What a mess...anyway, they had bought a new Dell with SBS 2K3 on it, and for some reason they have a wired firewall (Linksys), a wireless router (Linksys) and a small switch. After examining the setup of the network, I found the wireless router giving out IP addresses in the 192.168.1.X range, the SBS being what it is, was going to be the DNS/DHCP/DC, on and on, etc. I turned off the DHCP on the wireless router. Yesterday they called and had a machine that I wasn't aware of that couldn't connect, it's a proprietary machine for X-Rays, and all I could do was really look at it, and do a few things, like change the IP if needed, but it's set to DHCP, and it's getting 192.168.1.X addressing, when umm, it can't be. I did ipconfig /release then /renew, nothing, still the old address, with 192.168.1.1 as the DCHP and gateway. I statically set it to the 192.168.0.X settings and nothing, can't ping in or out or see the network. I set it back to DCHP reboot, and it still gets 192.168.1.X address, but there is no DHCP server serving up these address, so ummm, anyone? Oh, the X-Ray comp is plugged directly into the firewall now wich is on the 192.168.0.X network on the inside.......

I have run some tests and the IPv4 and IPv6 say they have no internet access
I also run a full test and everything passed except the ping test which failed and it said:

it suggested disabling security firewall but i'm not sure if that's the correct thing to do or even how to do that!

Hi all, sorry if this is in the wrong section but it was the closest one I can find.

I am setting up a Windows Server 2008 R2 server onto a network. The network has an ADSL modem router. I think I am setting up something incorrectly as I cannot get internet on my computers when the DHCP is enabled on the computer and not on the router.

My settings are as follows.

Server PC: (I set these myself manually)

IP Address: 192.168.2.1
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1

DNS Server: 192.168.2.1


Router:

IP Address: 192.168.2.2
DHCP Server: Disabled
WAN DNS Address: *retrieve automatically from service provider*

DHCP settings in server manager:

IP Range: 192.168.2.10 --> 192.168.2.100
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1
DNS Server: 192.168.2.1

I have not modified any DNS settings not entered any settings apart from the above.

I cannot for the life of me get the internet to work with these settings and I need to run a domain environment from this server so I need the DHCP and DNS to operate from the server.

If anyone is able to help me I will be eternally greatful.

Thanks
Mick

A:[SOLVED] DHCP and DNS in Windows Server 2008

Looks like your Server's setup in a loop, pointing back at itself for DNS (and Default Gateway?); you need it to pickup from an outside DNS server - your ISP, OpenDNS or whatever.

Not sure what the gateway needs to be set for, I'd suspect it should point to the router's IP - but I know almost zero about setting up a server!

Well, let's do the official stack repair, since you didn't say exactly what you did.

TCP/IP stack repair options for use with Vista or Windows 7.

Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

In the command prompt window that opens, type type the following commands:

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.


Next, if that doesn't do it, I'd suggest a run with SFC since it's saying a file isn't found.

I keep getting "local only" and "limited conectivity".I realized that the problem is in my pc because the other pc's connect to the access point without problems.I tested the following:

plugged directly to the modem=no success
plugged to the wireless routher=no success

When i looked into the info from ipconfig command i get this ip:
autconfigured ipv4 169.254.15.197

Due to that i entered ip manually something like:
192.168.1.2
255.255.255.0 and default getaway 192.168.1.1
then tried with disabled ipv6
Still nothing.Then tried netsh int test reset ip and netsh winsock reset catalog without success!
The i upgraded my wireless card drivers and routher firmware just in case,reseted the routher to factory defaults and still nothing! I really dont know what could be the reason for that.Since i bought the laptop 1,6 year ago didnt had any problems.
I think everything started after i uninstaled Norton Internet Security and using Norton cleaning utility! I instaled Eset smart security and i started to get blue screen of dead! I wasnt able to log on to windows.After uninstalation i was unable to connect to internet.

Greetings,
  I have several windows 8.1 machines connected to a private network.  The clients all obtain their first DHCP leases correctly and work well for a time. At some point after having been running for awhile, they get into a state where they start
ignoring the DHCP ACK messages from the DHCP server when they attempt to renew their leases (see attached pcap file).  They go on ignoring the responses to their DHCP Requests until they lose their IP addresses and then send a DHCP Discover and receive
a DHCP Offer.  At this point, they seem to accept their new address and move on until it is time to renew again, at which point they start ignoring their DHCP ACKs again and the cycle continues.  These machines will work for hours with no problems
whatsoever, but they all seem to experience this issue at some point every day.  When they get into the state where they are ignoring their DHCP acks, they will stay that way until they are rebooted.  Disabling and then re-enabling the adapter does
not seem to fix the issue.
 Does anyone have any idea what could be going on?  I'm pretty stumped at this point.

Thank you,
  Jason

We have DHCP setup on our server. Recently, however, when I go in to look at it, it says it is not started, or sometimes the DHCP server has deleted itself.

I'm not sure why it won't start, or even deletes itself. Any ideas on what is going on?

To get straight to the point, I've got network connectivity but no internet connection. ipconfig /renew gives the message "An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out."

I'm volunteering at a library. I just replaced one of the old public computers with a new Dell running Windows 7. They're all on a wired connection, and the old ones work fine. The new one is the only one with a problem.

This is a problem that has been annoying me for some time now...

I'm running a network of about 150 winXP clients, about 30 of which are laptops that may connect via two NICs at times (wifi and LAN). I have DHCP and DNS sitting on windows server 2003v2 AD Domain Controller with a scope of 512 addresses.

What seems to happen (still no idea why after many hours poking around) is that suddenly an IP address (often on a wifi NIC, but sometimes on a wired NIC) will become unable to reach the domain controller. By this I mean network shares become inaccessible, users cannot log on and I cannot ping the server from the client or the client from the server.

However I can still ping other clients; from the server and the client with the problem. Furthermore it is often the case that the other NIC on the problematic client will be able to maintain the connection no problem. As it has a different IP address it is able to reach the DC with no problem.

So what is basically happening is that the communication between a specific client and the DC only is being blocked somehow! I'm tearing my hair out! It doesnt make sense.

My only solution so far (which works everytime) is to set up an exclusion on the IP address this is occuring on and then renew the connection on the client. Now, this does not even work first time and I often have to exclude a string of IP addresses temporarily until I find one that allows full communication!

Got a Dell 4100 PC with WinXP SP1 (but missing some rec and crit updates), Norton AV with AV defs that are approx 3 weeks old, Norton Personal FW, an SMC wireless NIC and an SMC AP/broadband router.

Problem is Dell PC can not connect to AP using DHCP. Other PCs in home connect fine. Status of SMC NIC in Dell PC indicates packet xmit but no packet rx. ipconfig reveals 169 ip address because no packet rx response from DHCP in AP. I assigned static ip address, net mask, and gateway. Can ping loopback, and can ping AP, but can't ping Internet. Another ipconfig reveals ip address and net mask are assigned, but no gateway. Also noticed that in ping output, filled in greater than symbol (>) replaces ip address in "pinging 'ip address' with 32 bytes..." text. Other chars replace ip address in "ping statistics for ip address:" in same ping output. Lastly, if I attempt to start IE, it opens but immediately shuts down with no error messages. Turned off Norton Per FW, no change.

PC is mainly used by teenager. Alot of spyware/adware/malware. Spykiller was installed and run previously. PC worked for a while after Spykiller run. I'm thinking virus, but nothing detected with 3 week old defs. Short of a format and re-install of XP, I'm looking for some possible solutions. Thanks.

We are moving our DHCP from one Windows 2003 Server (standard) to a new machine. Both servers are domain controllers. AD is set up and working on both servers. Everything is set up. I exported the dhcp database from the old server to the new one. All messages were successful.

I unauthorized the DHCP server on the old server.

Now when I try to Authorize the new DHCP server, I get an Access Denied message. Everything I have read is indicating that the I have to be a member of the Enterprise Admins group in order to Authorize a DHCP server.

We didn't have this group initially and I'm thinking we didn't because we are only running Server 2003 Standard. I created the group, but I'm not sure if I did it right and added Administrator. It still isn't working. Can someone please help me?

Hello

I hope you guys can help me, sorry this is very long and clueless. I am not techy at all.

I have 2 PC's connected via ethernet cable to a router provided by my ISP (Orange Livebox). One PC has Windows XP (hubby's) and one has Windows 7 (mine).

Until about 2 weeks ago both PC's were working fine and no internet connection problems. We lost our connection one Friday night along with thousands of other people in our area. It was fixed on Saturday but ever since then my PC has been dropping it's internet connection but my husband's PC is working normally.

My internet connection drops and will only come back on if I unplug the router and leave it off for a minute then plug it back in. Connection then works for a few hours (usually up to 7 or 8 hours) before dropping again.

I get this error in the Event Viewer when it happens:

Have contacted the ISP "support" who sent a new Livebox and ethernet cables. I thought this had worked but lost the connection again the next day.

Yesterday out of the blue my Internet connection on my laptop became screwy - very slow and disconnects frequently. My other devices (iPad and iPhone) are connecting to the wireless signal with no issues.
Reading other posts, I have tried several things, including changing the channel on the router (net gear router with auto select for the channel) and uninstalling my virus software for any firewalls that may be causing. Before uninstalling I also ran a full scan and it detected no viruses.
I reset the tcp/ip.
I also downloaded the Xirrus wifi inspector, and the connection test is variable every time I run it - sometimes all pass, but usually there's high latency in the different categories.
Any further advice would be much appreciated!
 

A:Ping failure for gateway and dhcp and Dns

Try resetting (power cycling) the netgear router, and see if that clears things up. I had a netgear with similar problems, and resetting it would take care of the issue. For a while. Also make sure you have the latest firmware for your netgear router - you can download it directly from www.netgear.com

Ended up getting a Cisco firewall/router as a replacement, and never had any problems with that....

My laptop is running Vista SP2. The machine will connect to my Belkin router with a wired connection but I have a problem setting up a wireless connection. The machine can successfully obtain an IP address from the DHCP server but it is unable to get a ping response from the gateway address or anything else on the LAN (and yes, other devices on the LAN can ping the gateway 192.168.2.1). I have tried stopping the Base Filtering Engine, running 'netsh winsock reset' and applying the fix in http://support.microsoft.com/kb/928233 but none of these has resolved the problem.

In the 'Network and Sharing Center' window, the machine is shown as being connected to 'Unidentified network', but there is a red 'X' against the onward connection to the internet. Initially, I had the same problem with the wired connection but running 'netsh winsock reset' in the command window triggered it into creating a new network location the next time it connected and then it worked happily. Unfortunately, I have not been able to repeat this with the wireless connection.

The network adapter is an Atheros AR5007EG with driver version 7.3.1.109 and the status show that is working properly. For information I have shown below the output from the command ipconfig /all:

Welcome to TSG.
We have seen quite a few issues with that adapter.
Here is a summary of things to try:

We have recently been seeing a lot of problems with the above adapters over the last few months, mainly concerning WPA and WPA2 encryption and windows Vista.

The adapter gets an IP configuration, and shows as connected, but communication is non-existent or sporadic.

Log into the Router and disable the wireless security and see if you are now able to connect to the internet and surf OK.
--- Please post back here if that works or does not work.

Here are a number of possible solutions

--- 1) In Device Manager right click on the wireless adapter and "update driver." That apparently has worked for some posters.

--- 2) Download and install the latest wireless driver from your laptop manufacturer's web site support section, as some manufactures, appear to now have a working driver available.

When logging onto the company network via a RAS server, the DHCP active leases is not being updated with the IP address assigned to me. This is the case both when the RAS server is configured to give an IP address from a fixed pool, or when configured to obtain IP address from DHCP. As a result, I'm experiencing problems if an existing lan device has an IP address assigned and the dialed in device grabs that address. Whats going on ?
 

A:{Solved} - DHCP active leases not being updated when dialing into network via RAS server

Greetings

There should be a clear distinction between the IP adresses available for the network, and those available for the Dial up users. Do not make them part of the same IP group.

The reason is that Dial-up IP addresses should have a lease time of a few hours, and the LAN lease time should be that of a few days. This is obviously not compatible, so they need to be seperate.

Hope this helps

Hi,
My old hard disk was dead so bought a new hard disk drive of 500gb, when i tried to install windows xp on the new hard disk the cd didn't boot as it used to do first, it gives out an error during boot "PXE-E51: No DHCP or proxy DHCP offers were received please enter bootable device and press any key". Thanks in advance.

A:PXE-E51: No DHCP or proxy DHCP offers were received

Any message such as this referencing 'PXE" are likely indications that you need to adjust the boot device settings in the BIOS.  The message indicates that the system is currently trying to boot via network, rather than boot to an optical drive or a hard drive.
 
If you want to boot from a CD to install XP, then the first boot option in the BIOS must be changed to an optical drive.
 
If you want to boot from the hard drive, then the first boot device should be changed to reflect the hard drive as the first option.
 
What makes you think that your old hard drive was dead?
 
These PXE errors are often the result of the fact that the CMOS battery is dying or is dead and needs to be replaced.  Since this is a vital but cheap item easily obtained, this is not a serious problem.

I'm having a terrible time with one win 7 32 bit computer on my home network. All other devices (about 12) work fine, other windows 7 pc works fine, ADSL router and Cisco switch work fine. This one Dell Vostro 430 with a cable into the network worked fine for 2 years. Overnight it can't connect to local network with its DHCP settings and if I change to static ip it still can't browse the internet. However I can ping external addresses by IP address only. If I ping google.com eg it cannot find the host. What is really confusing is the "Ping Statistics for " response contains neither the name or the address but instead random characters... ie $5 this changes every time. all other devices on the same network resolve IP adresses to their fully qualified domain name.

Our ISP just installed a DHCP server (we won't be using it, we have static IP address for internet). Our NT box has two NIC cards, one for local network, the other connected to our cable modem. It has DHCP server running for our local workstations to get their ip addresses. But it has been shutting down with an error message stating that "The DHCP server is shutting down because another DHCP server with IP address of 172.29.0.2 is active on the network." 172.29.0.2 is our ISP's new DHCP server. How can I get our server to ignore the ISP's DHCP server?
 

A:ISP DHCP shutting down internal DHCP

You need to make sure your ISP isn't trying to renew the DHCP lease and has your IP address excluded from their DHCP servers list of non static IP's. Sounds like their error and config problem not yours. Unless you haven't excluded your static addresses from your DHCP server pool.

Right now I have my server connected to a router and the router does the dhcp for me. I am thinking of putting a second nic in the server and using it for dhcp. If I have computers in the house that are not a part of my domain will I still be able to get online with them if they are connected to my switch? I guess to paraphrase myself I am asking can you use a server to route and not have everyone connected to the server in your domain?
 

A:Server DHCP or No

I'm not sure what DHCP has to do with routing... Are you trying to break your network into subnets?

You wouldn't need a second NIC to move DHCP to your server. If you want to move DHCP from your router to your server, just set up a new DHCP scope on the server and that's all that's required. Clients do not have to be part of the domain to get an address from a DHCP server.

Here is my current configuration:

We have 7MB/768K DSL Business dynamic IP connection.
Anywhere from 10-20 simultaneous users.
One Cisco 30 port switch feeding into one Linksys wireless router to provide local IP addresses to all the users for the one IP address to the world.

Are there any low cost solutions that would provide faster performance for the users?

Hi skibizkit, and welcome to TSG.

skibizkit said:

... provide local IP addresses to all the users for the one IP address to the world.

It seems to me we have a huge bottleneck at the wireless router but we need it for the DHCP server in that router.Click to expand...

Sharing a single Public (world) IP address with multiple Private (local) IP addresses will require some type of router that supports NAT (Network Address Translation). Running a DHCP server on the router should only add a small amount of local bandwidth usage when a computer first connects to the router and gets assigned its private IP address by the DHCP server. The DHCP server is then out of the picture until another computer comes on line or the DHCP lease time (could be up several days) expires for each computer.

Is the speed bottleneck related to accessing the Internet through the DSL connection or exchanging data between computers (and servers) on the same local network?
