Can't connect to DHCP server

Q: Can't connect to DHCP server

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 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.

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 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.

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:

Desktop

-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

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.

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.

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.
As a possibly associated issue, since I believe Bluetooth also uses the Wireless PAN DHCP Server, I cannot get Bluetooth to function on the same computer. Attempts to connect Sony Bluetooth speakers also fail.  Maybe the same issue?

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.

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.

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.

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?

The reason for my post is because it stopped working again. I can't figure it out and it's driving me nuts. Could this be an issue with the setting where you can select which network your own for example work, home or public location?

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.

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

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

A:DHCP Server (Do I need one?)

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?

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.

Is it better to have my win2k server distribute IP's, or my my router? Is there a difference? Are there any benefits or drawbacks from doing it one way or the other? What would happen if both are set for DHCP? Thanks

Hello everyone!

I'm new to this site and I've searched for a topic related to my problem, but couldn't find anything.

I had Norton Internet Security 2005 installed on my computer, but when I added a new hardware item to it, I had to uninstall NIS and re-install it because it wouldn't work. After rebooting, I couldn't establish an intranet connection that did work on the comp before. I managed to find out that there is no default gateway on the LAN, because "no DHCP server was found". To be honest, I don't even know what this exactly means, but anyway. Here's what I tried so far, and didn't work:

1. Restore the default winsock settings, with the netsh winsock reset catalog command and with downloaded winsockfix programs too.

2. Try to renew the IP-address by right-clicking on the LAN settings.

3. Reset TCP/IP stack to installation defaults, with the netsh int ip reset reset.log command.

I've got Windows XP Sp2 and a D-Link DSL-360T modem/router, with ethernet.

I would appreciate any help, but please write it in an "advice for dummies" way, I'm quite a newbie with technical issues. Thanks in advance for your help!

I use a Verizon USB broadband modem attached to my Vista Home Premium desktop using ICS thru a wireless network for internet access and a home network. The desktop is linked to the wireless by CAT5 cable to a regular port on the router. We can then connect my wife's XP and my Linux laptops wirelessly. The router has DHCP disabled and all networked machines get their ip thru ICS from the desktop. This has worked well for 2 years. Suddenly I get limited connectivity from my NIC and a private ip (169.xxx.xx.xx). I looked at the services and found the DHCP server had been stopped. When I tried to restart it as a network service I got an error stating "the account specified for this service is different from other services running in the same process." If I change the logon to Local Service I can restart the service but it still will not give the NIC a valid ip. I have tried to use the diagnose repair option from network and sharing center but it fails as well. Anyone have a suggestion on how to fix this?

A:ICS and DHCP server not working

May or may not work but a winsock reset can be helpful in these sort of issues.

1)Click on the Start Button
2)Type "cmd" in the start search area
3)At the top of the menu you see cmd icon, right click it and left click "run as administrator".
4)DOS window, in this window type this minus the quotes " netsh winsock reset "
5)Hit enter key on your keyboard.
6)Restart the computer.
Give this a shot and see if it helps.

If your PC is set to obtain an IP address automatically at boot up then it uses a DHCP broadcast system, this system sends a DHCP request via the network software through the network card and through the network cable out on to the network, if a DHCP server is available then it will reply and your PC will be given an IP address by the DHCP server,

DHCP servers can be a router, a PC running Internet Connection Sharing, or a PC running a DHCP client (such as on windows 2003 server).


If your PC cant find an DHCP server and you have it plugged into a DHCP server then either the cable is wrong or faulty, or the DHCP server is not seeing the PC.

Please post back saying what exactly you are trying to achieve.

I have a vista home premium laptop I have been trying to connect to the internet using wifi. I have an xp desktop that connects quickly. My laptop says there is no response to the dhcp server. Can you help me fix this?

A:DHCP server no responce

Hi -

Let's see what your system can tell us about the wifi situation. Please download the EXE file - save to Documents. RIGHT-click on EXE file, select "Run as Administrator"

2 Notepads will open one behind the other. Save both as text files. Attach to your next post.

Also, try booting into SAFEMODE w/ Networking and try Internet connection there.

Do you have Internet Security suite installed - w/ 3rd party firewall?

Regards. . .

Hi,
I was created a DHCP server in Server-2008 r2 but it didn't provide IP automatically to client and on the other way in the roles sections when I click on DHCP, it didn't expand as other roles expand.
Please provide the solution.
Thanks,

Is it okay or dangerous to trust my wireless router?

A:Is it okay to trust the DHCP Server?

The IP address 192.168.0.1 is the default for certain home broadband routers, principally various D-Link and Netgear models. This address is set by the manufacturer at the factory, but you can change it at any time using the network router's administrative console.http://compnetworking.about.com/od/routers...168_0_1_def.htmBut also see http://www.bleepingcomputer.com/forums/top...tml#entry999836

Work in school with about 35 w98 clients and nt 4 server, recently had broadband installed so I had to change the IP address on the server as requested by broadband company then set up new dhcp scope for clients. Server reboots with new ip but cannot release and renew ip addresses on clients. (I had logged them all on ready.) Activated and reactiveted scope, changed ip back to orginal it all works but when you change it back to new settings clients can't see server, I gave one client a static address from the new range (an excluded number) and it logs on sweet as a nut - so I'm thinking dhcp problem. Also when I do IPconfig on server it gives 2 nic addresses for one mac address why?Any help would be appreciated!
 

A:nt server dhcp problems

Begining is the best solution!! hehe! So, You should do your DHCP as a new one, anyway, you were given a new IP, so it's absolutely new, isn't it!
Try mine!
Seperate DHCP from network, simply unplug the connector!
Stop DNS, delete your DHCP scope.
Uninstall, yes, uninstall you NIC!
NEXT! Do it in reverse!
Reinstall you NIC by restarting Windows! type cmd in Run command and ipconfig /all. How many NIC you have now? ( ofcourse, after you set the static IP, subnet...)
Restart DNS.
Create new DHCP scope, activevate,... ( Be sure you do it completely right).
Now, renew until DHCP work, ( Until you see the green light, you knew it).
Now, test DHCP in client by plug the connector!
Try this first!

My internet browsing has slowed to a crawl and I cannot access web meetings and other sites I have subscribed to. I did some system testing and everything came back normal except for the following: VIA Compatible Fast Ethernet Adapter: failed DHCP Server = 10.230.40.14: failed pinging 10.230.40.14 w/32 bytes of data request timed out (this is repeated 4 times) ping statistics for 10.230.40.14 packets: send=4 received=o How can I fix this failure? Is this DHCP server from the browser; from my internet provider? Who issues this protocol number and can I change it, do I need to change it? When my computer is running the way it should it is fast and the problem with it acting so slow was intermittent for a while, now it is constant.
I use windows XP
