All the users on my network recieve the same error when they boot up and log on:

Event Type:      Warning
Event Source: Dhcp
Event Category: None
Event ID: 1003

Description:
Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address XXX.  The following error occurred:
The semaphore timeout period has expired. . Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

My servers are all Server 2003 and worstations are all XP with the latest service packs applied. What could be causing this?

Sorry for that question, but did you set up a DHCP server somewhere?

If not, just do that. ;-)

If yes, did anything change in your network? For example did you install new switches or something similar. This problem can occur if the switchports are configured for a fixed speed/duplex instead of setting the speed/duplex to auto.

When did the problem start?

DHCP is setup on my DC.

The problem has been occuring for about 4 months now. Nothing has changed in my network, as far as I can tell.

Nevertheless check the speed and duplex settings of your NICs and switchports and make sure they are not set to a fixed value.
