DNS settings changing

[Screwdriver13]

Hello,

All of the machines on my network are Windows XP SP2, 70% logon to a
Win2K3 domain the other 30% do not. They all get the TCP/IP setting
from a DHCP server. At first all the settings are correct. However,
about an hour later any machine on the Domain has the DNS settings
changed to IP addresses for our old DNS servers. The machines not on
the domain stay correct. We only have one DHCP server on the network.
I tried to see if there was a GPO making the change but we do not have
any GPOs that set the DNS servers on client machines. Is there a way
to track or log what is changing the TCP/IP settings on a Windows XP
machine. I'm starting to pull all my hear out.

Thanks,
Joe

This "seems" to indicate that there MIGHT be still a second DHCP running? Are
your 100% sure that there is only one??? Did you check the DOMAIN servers????

If there was a second DHCP server, the machines not on the domain would
also get the DNS settings changed. Right now it is only happening on
the machines that are on our Win2K3 domain.

Thanks,
