unable to contact your dhcp server

[timwegen]

I have a problem with the LAN-connection of my desktop with WINXP/SP2, while the connection (with the same cable) works perfectly on my laptop. I get my internet via a Arris TM502G modem.
The connection of my desktop gives the following status: “Limited or no connectivity”. When I try to repair the connection it gives says that it can’t “Renew IP Address”. When I run ipconfig/renew it gives “unable to contact your DHCP server” as result.

With the internet cable plugged gives ipconfig/all the following info:

Powercycling of the modem doesn't work. As well as the following commands:

Reset CP/IP stack to installation defaults, type: netsh int ip reset reset.log

Reset WINSOCK entries to installation defaults, type: netsh winsock reset catalog


Since the reinstallation of Windows XP Ipconfig/all says that the dhcp server is unabled.

Was this computer working previously?

Check that the DHCP service is running (start > control panel > administrative tools > services) and scan for viruses and malware. DHCP should be set to automatic or enabled.
