XP PCs pulling wrong DNS address

I have discovered that our XP machines (at least 3 of them) have pulled the
wrong DNS address from our Windows 2003 DHCP server. The correct address is
10.110.0.158 and they are pulling 192.168.15.1. I have tested the network
and found no rogue dhcp servers and a renew command fixes the problem (for a
while). My lease time is 8 days and I confirmed that they got all other dhcp
info correctly from our dhcp server... only the dns was wrong. Also, no
windows 2000 workstations have been affected (yet).

I am stumped on this one. Anyone have any suggestions?

Thanks,
Marc

That looks like an IP from a router. Is there anything on your network using
that IP? If not look for someone setting up their own wireless access point.

Thanks for the response. I did indeed find a Vontage router on the network
and I think that was it.
