This is a windows server 2003 network. I have two XP Pro workstations that intermittently cannot authenticate to the domain. If I login locally and browse entire network, I can see the domain, the server, and authenticate to the server. If I go to control panel, system, I can change the network settings on the workstation to member of work group "ABC". Reboot the system, then go back to control panel, system and change network settings back to member of domain "xyz.local" reboot and authenticate to the domain. It's very strange that sometimes it works and sometimes it doesn't.
All the workstations are setup for DHCP. IPconfig /all shows three servers. First one is IP address of server (192.168.1.253) first, then lists IP address of comcast's DNS servers. I can go to a DOS prompt and ping "xyz.local" and get a reply from the IP address of the server.
This is perplexing!
