We have a Windows 2003 network. Our DHCP server seems to work fine for the computers that are already setup, it can hand out IPs correctly and whatnot. But when someone brings in there laptop for some reason they get assigned an IP address that is out of our lease scope (We give out 10.10.2.1 - 10.10.3.50), for example they would get 10.10.3.230. Also they would get a default gateway of 10.10.3.210 which used to be the IP address of one of our citrix servers.
In DHCP there is a setting for "router" with the proper default gateway in the scope. I have no idea why it is handing this information out.
There is no other DHCP server running.
We also have 2 DNS servers, one of them has an NT4 OS the other has W2K3, one external and one internal.
Please help, this is very innoying.
