DNS/DHCP Weirdness

[ChrisM]

Hope this is the right place to ask. If anyone knows of a more suitable
group, please tell me.

Anyway, having this strange problem with my XP machine.
It's on a network with a SBS2003 server which is acting as a DHCP and local
DNS server.

Initially, all is well, and if I type ipconfig/all my computer shows
xxx.xxx.16.1 for the DNS Server (which is correct). After a short period of
time (1-2 hours) I find that my internet connection stops working, and on
investigation (with another ipconfig/all) I find that my DNS server has been
reset to xxx.xxx.0.1 !!
If I then run ipconfig/registerdns to refresh my DHCP lease and re-register
DNS names then the DNS server is back to xxx.xxx.16.1 and all is well... for
the next 1-2 hours...

Anyone got any ideas why this keeps happening??
