constant dhcp requests

Unread postby tuvia » October 26th, 2010, 4:52 pm

the Win2003 server sends constant dhcp requests to the dhcp server (port 68 I think). It gets all available IP addresses, then still keeps sending, so it gets any more addresses if they open up. The dhcp server shows all the ip addresses issued to the server's mac address, and port scanning shows the constant requests. The requests come services.exe which loads the network services, obviously an essential service.

Malwayebytes, spy-bot, AVG, clamwirus cannot find the problem.

Here is the hijack log, maybe it will help:
