WINXP Pro loses DNS setting on reboot IP is manually configured

Alright I have looked high and low for this one and I cant find anything as to why its happening.Ok here it is, I manually configure my workstation (pc) with a static IP 192.168.1.201 mask 255.255.255.0 gateway 192.168.1.1 and the DNS is set to 192.168.1.1 (using router). – All work perfectly fine except when I have to reboot. After a cold boot the DNS settings on are blanked out but all the other settings are fine. I can ping locally obviously nothing DNS. I think but cant be sure that this started with SP3 upgrade.. can anyone HELP, its just getting annoying.
