I have come across a problem at one of our sites.
The Server is running 2K3 SP2, it is the DC and is also running DHCP and DNS on the server. There is a Single NIC in the server.
The problem we are having is that the pc's on the domain are picking up addresses but we are unable to ping anything from these pc's, this is not on all pc's all the time but seems completely random. The ip address' that they are getting are all correct, in the DHCP range, right subnet mask, gateway and DNS servers etc.
I found in the DNS host records a reference to the server with a different address which has been deleted.
Hope you can help with some suggestions
