Network could not connect to DHCP server

Q: Network could not connect to DHCP server

I am running windows xp on a dell inspiron 4150 with a built in wireless card. My wireless was working fine until windows prompted me to reboot due to windows update. It stopped working after that. It is telling me that no ip address can be found and when I ipconfiged it with renew and all it still could not find it. It gave me an error message that says cannot connect to DHCP server.
Any help will be appreciated.
Thank you,

Preferred Solution: Network could not connect to DHCP server

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.)

A: Network could not connect to DHCP server

Nothing really comes to mind, but if you're using Window's Wireless Zero Configuration maybe you need to reconfigure your wireless connection; especially if your network is protected with encryption.

I use the utilities from my wireless cards' manufacturers to connect to my WPA protectecd network and had no trouble today after the same reboot (two notebooks). Well, same reboot if you're talking about the critical update released yesterday.

I just got Cox cable and it hasn't been working right.

I have a netgear WG602 wireless access point. I can connect to it but it has limited or no connectivity. Repairing the connection doesn't work and doesn't give me an IP.

I connected the ethernet cable directly to my laptop and it didn't work at all. I called them and it worked by directly connecting, but the wireless still didn't work.

Then I messed with wireless settings to try to connect, and I finally got online but my ip is 70.x.x.x, the apparent IP for all Cox subscribers.

But I got that 70.x.x.x through my router instead of a 192.x.x.x so I have no idea why it's doing that. It's really weird and I still can't get a dynamic IP.

Thanks for the help.

I got a new desktop loaded with Microsoft Vista.

When I couldn't connect to my router (at home) I tried ipconfig /renew /reliease commands and got the following message:

"Unable to contact your DHCP server".

I brought my PC to work and it connected fine to the network there.

At home I use the modem/router provided by Verizon (FIOS). I tried several ethernet cables - so I am pretty sure it is not the cable.

BTW, other pc's at home are connected to the router, so the router is OK.

Any help is appreciated.

Check the setting on your Router which served as your DHCP as well. Make sure that the Router provides enough IP addresses for your home network.

Hi Guys,

I have been experiencing some irritating problems with my internet and creating a hosted network for my mobile devices. creating a hosted network was easy and has worked for quite some time until this weekend. Doing some quick google searches almost all the results said I should release then renew my ipconfig, and this is where all the real problems started. It won't renew and from there my problems keep coming.

My connection is provided by my university so there is no way for me to quickly reset the modem.

To Whom This May Concern:

I tried installing SP1 on a desktop Vista, with other windows updates, and my internet stopped working. My Xbox and another computer (XP SP2) work fine and haven't noticed a difference.

I've contacted my manufacturer, and they said uninstall everything. I did. There is one Windows Update and one Microsoft .NET Framework 3.5 SP1 that it won't let me uninstall. I've contacted my ISP and they said there's a problem between my modem and hub, but if that's the case, my other computers wouldn't be working either.

I've contacted Microsoft, several people, and after many procedures, concluded that I need a restore disk and set it back to factory settings. This is an absolute last resort.

Here are my specs:
Vista Home Premium
Desktop
AVG 8.5
Comodo Firewall
XtremeGamer SoundCard
I don't know what else is important since the computer has worked for a year before attempting SP1

Here's what I've tried:
-ipconfig release, renew
-enable and disable dhcp broadcast flag via regedit
-exchanging cables, all cables work with other computers
-netsh resets
-clean startup tray
-closing viruscan and firewall, leaving one open, all possible combinations thereof
-power cycling the modem and hub

Hello
I would like to ask for help

I'm having a issue with the wireless in the past couple of days before it has always connected in seconds. when starting up the laptop it takes 1-2 minutes to connect (blue circle loading) but the connection is not stable such as random times disconnects (turns off itself) and the signal strength is pretty weak(looking at task manager 10-15mbps). Once the wireless stabilize which is around 15 minutes it can reach back to normal speed.


I went into the event viewer and noticed the laptop has this warning message + error message

Error message: The IP address lease 192.168.1.3 for the network address 0x001D0981E03A has been denied by the DHCP server 192.168.1.1(The DHCP server sent a DHCPNACK message).


Another message:Router Advertisement settings have been changed on the network adapter 13. The current M - Managed Address Configuration flag is false and the O - Other Stateful Configuration flag is false. User Action: If you are seeing this event frequently, then it could be due to frequent change in M and O flag settings on the router in the network. Please contact your network administrator to have it resolved.

Hello Everyone,

We our setting up a Training Company to assist unemployed IT people in the Silicon Valley area of California. Our group is very small and having a hard time even getting our network here started. Here is the problem: We have Windows 2003 Server Enterprise 180-day usage disc (from a book we bought to learn). We have 5 static IP addresses leased from DSL carrier. They are for example: 65.123.141.10 thru 65.123.141.14 with a gateway of 65.123.141.9 [these are only IP numbers used for example to prevent hacking] my subnet mask is 255.255.255.248 We tried and tried for 2 weeks now and still can not get the complete network to work. We need: Step1.) The server to be secure with a firewall (but willing to forgo that and add later) Step2.) the server to issue Ip addresses from a pool of 192.168.0.10 thru 12 to 3 workstations running XP(we decided to make the server 192.168.0.5, subnet mask is 255.255.255.0 and gateway 192.168.0.1 Step3.) Have access to the internet on all workstations and the server too. All we have succeeded to do is get the dhcp to issue out addressses to the workstations and even that i think we got lucky. We think the problem is somewhere you need to tell the (maybe iprouting?) setup that the Public ip address is the 65.123.141.10 and gateway, subnet info and to route to the server PRIVATE ip address 192.168.0.5

Hi folks,

As I've said in the title, I'm looking to make a network with two routers but only having DHCP enabled on the secondary router.

Before I go any further I must ask: I have an Arris GT840A (sigh) as the primary ISP required modem. I'm currently connecting via wifi and sometimes have pings to the router coming back in the 1 - 20ms range for extended periods and it's decent. Other times I get a huge range of different ping times, often in the 300ms - 6,000ms range and sometimes even dropped.

Is disabling the DHCP server on the modem and relegating all local networking duties to my WRT54GV2 likely to alleviate this problem, or does this simply boil down to I'm screwed because I have to use this Arris modem?

Moving on with the primary question, here is my current setup:

Router 1: Arris GT840A
WAN IP: Dynamic / ISP assigned
LAN IP: 192.168.0.1
DHCP: Enabled
192.168.0.2 - 50

Router 2: WRT54GV2 (Connected to router 1 via WAN port)
WAN IP: 192.168.0.51
LAN IP: 192.168.1.1
DHCP: Enabled
192.168.1.2 - 50

With my current setup I have been able to ping both router 1 and 2 via wifi, but I have not been able to ping or connect to the internet at large. I have read a couple of different how-to's and other forum answers and feel like this is how I'm supposed to be setting it up, but it's still not working. Something that concerns me about this attempted setup is that it still is using DHCP from the Arris modem / router, and I'm r... Read more

I purchased a Netgear Push2TV PTV3000, and updated the firmware, downloaded the latest Intel WiDi, and tried to connect. The search for WiDi adapters found the PTV3000, so I double-clicked to install it. Add a Device ran, but could not find the PTV3000.
Searching the Web I found I needed to insure WiDiApp and Wireless PAN DHCP Server were allowed through the firewall. I found that the WiDiApp was listed in, and allowed through the firewall. I could not find any mention of Wireless PAN DHCP Server in the firewall.
I found the entry in Services, and it was listed as Manual. I set it to Automatic and tried to Start the service. I received an Error 1067: The process terminated unexpectedly.  I am running Windows 8 on a Sony SVS15118FXB.

Hello. I just moved to Auckland, NZ from the USA to go to school at the university here, and am having a problem connecting to the internet in the university residence hall in which I am living.
Wifi is not available in the residence halls, so we need to use an Ethernet cable. When I plug in my computer, the network adapter icon says “Identifying...” for a while then settles on “Unidentified Network” with no internet access, the IP is 169.x.x.x
When I try to release and renew the IP, it says “unable to contact your DHCP server, request has timed out"
I've tried multiple Ethernet cables, both brand new.
I tried connecting to a port in a friend's room in the same building, and even in a classroom on campus, and both had the same result.
Naturally after all that I assumed my NIC somehow died overnight while I traveled here, so I went to a computer repair shop expecting to have some hardware replaced, but we plugged it in there and it worked immediately so they weren't sure what to tell me.
I've gone through pages of old threads at this forum and others like it, trying solutions but having no luck.
I've power cycled my computer, obviously I can't power cycle the whole network as it's for 200 people, but the IT people here have tried resetting it for me on their end as best they can.

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

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.

Hi guys and gals,

i live in a student house, and we have a wireless network but my laptop can't connect to it. the lan works fine on my laptop, and my laptop can connect to a few of our neighbours unsecured networks. 3 other laptops in the house have no problem connecting to our wireless, but my laptop wont.

i opened a command prompt and did ipconfig/release then ipconfig/renew and this message came up: An error occurred while renewing interface Wireless Connection : unable to contact your DHCP server. Request has timed out.

when i try to connect to it in the list of available wireless networks, it acquires network address for a while, then says limited or no connectivity. i click repair, and it says " Windows could not finish repairing the problem because the following action cannot be completed: Renewing your IP address. For assistance, contact the person who manages your network." ... and im the most computer literate person we've got

Hi!

My daughter got a virus on her laptop and after getting rid of it (I think all the way, it's hard to tell until I can update the anti-virus software) I can no longer connect her laptop to the internet.

I have had a problem in the past with having to reboot the server and all the computers in order for the computers (all of them in the house) to register new ip addresses. Normally, if I have one computer that refuses to connect even after a reboot of the entire system I can connect it thru LAN and it, bang, fixes itself. However, this time it is not working.

Not only will her wireless not connect but neither will the LAN. I have opened the cmd prompt and done an ipconfig/release and ipconfig/renew. Every time I do this I get the message:

"An error occurred while renewing interface Wireless Connection : unable to contact your DHCP server. Request has timed out."

I tried the "netsh int ip reset resetlog.txt" and it seemed to work fine.

I also tried the "netsh winsock reset" and it seemed to work fine as well.

I rebooted each time I attempted a fix. Still I am unable to connect to the internet. It says it is connecting locally, but will not connect to the actual internet. When I use the repair option it gives me the same messages over and over that do not work. It always leads back to the IP address.

Here are the specs on her computer and as much information as I can think of. Please let me know what else I can try to get her compu... Read more

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.

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?

times on various computers range from good (1-2 minutes) to very bad (5-60). Our second time logons range from 30 seconds to 4 minutes. We have a gigabit connection between each computer on the network. We have 5 domain controllers which also double as our

You have to tell us what network you are connecting to so you can get help. No info = no help.

You could start by describing physically how your computer connects to the lan and then the internet.

On the other hand, the DNS console remembers that I've used a particular DNS server even after I close the console.

Hi I am trying to use the FTP client integrated into windows 7 to connect to a local server all the other machines on this network can connect to. All the settings seem the same. The server allows 50 concurrent connections. I am not sure why this one machine (LAN over Gigabit Switch) can't connect with the same credentials as all other machines on the network. I've looked at the firewall settings and allowed port 21 for the negotiation of the connection and listing the directory.

I am going to make a new user and password and see if that solves it.

A:Can't connect to FTP Server from one PC on the Network

Problem is solved. Anyone know why that could be? Does the client keep every machine logged in all the time and only so many connections are allowed from each user? This is a question for the CrushFTP forum now!

Hi Guys, I have read a number of posts here about networking issues but none seemed specific to my issue... I had a Windows 7 environment and just recently purchased a Windows 8 laptop.. .well win 8.1 Pro to be exact. On all of my windows 7 machines I can ping 192.168.1.199 and get solid response and go to that address in the browser and no issue. On the new Window 8.1 laptop I ping that address and sometimes get 1 timeout with 3 responses... other times it just times out and sometimes I get all 4 replies... The print server has a web interface but I am unable to connect to it at all - is there something I need to set in Win 8?

Welcome to Eight Forums,

This could be a network card driver issue and depending on the chipsets of your computer. Some Users have encountered disconnection issue after upgrading from 8 to 8.1, possible solution is to try downloading the latest driver for your network card from the manufacturer's site. Also, please check out this Thread.

For Broadcom NIC drivers try downloading the Windows 7 driver, check out this Thread.

I'm messing around with W2K Server at home and can't seem to get it connected through my cable modem to my ISP's DHCP server. I know the cable and connection are good because it works on my W2K Pro workstation. I've tried ipconfig /renew but that's when the error occurs that it can't find DHCP. I can successfully ping the loopback address. The NIC is set to use DHCP.

Since I'm just becoming familiar with Server I'm sure there's something I'm not configuring properly. Suggestions?

Thanks.

Hello. I am a complete newbie to server administration. At my current job, I have been tasked with setting up a deployment server. The server is a Windows 2008 server and is not connected to the Internet. The server is a domain controller on its own domain (different from the main domain my job uses). How would I connect this server to the Internet without disrupting other users on the network? By disrupting, I mean connecting to my server instead of the main server for DNS and DHCP. The server has Active Directory Domain Services, DNS, DHCP, and WDS roles set-up.

--I wasn't sure if home server was more based on XP or Vista, so i put it here--

hi all,
I have a router and a wireless internet connection, and i recently installed windows home server on an old desktop (something i've been meaning to do for quite some time). However, on the first bootup (when it had completely finished installation), It automatically loaded up an internet explorer page with a microsoft url. It said the page could not be displayed - great - No internet (sort of needed for a server).

I went to new network connection, and chose "always on", and it said it should already be working... chose repair. Well the thing is i don't know where the icon is that's usually in the system tray on XP and vista to connect to a wireless network.

How do i connect via to a wireless network?
Does it need to be plugged in directly via ethernet to my router?

Thanks,

home server was not designed to work wirelessly, this is explained within it's documentation. you do need to hard wire (cable) your home-server computer back to your network switch or router for it to log on and receive the internet. hope this helps

1. Map Network drive. I select a drive letter and type in the ip \\12.345.678.9\
It asks for credentials and I enter the user info for the user I created on the Linux machine. It thinks a moment then pops back up asking for credentials. It doesn't say they are invalid, just never goes through.
