I removed my backup server (server02) from the subnet it was serving to repair a bad disk. The workstations on that subnet show logonserver=server02 , and the only available server is server01 on a different subnet. How do I get the workstations to find the main server in the interim? When logging on , they now complain the the domain is not found. Server01 is found in dns, and the alternate dns server is specified as server01. Before I installed this backup server, all machines on the subnet used the main server by default.
