Is this feasible, why can or cant this work?
2 subnets, PDC on subnet A, and NT workstations on Subnet A and B. Can and how will a NT workstation on subnet B authenticate to the PDC on subnet A.
There is no WINS in place.

Within the same lan, Authentication can occur if you are running NetBuei. If not, then authentication is not possible

The problem lies in the workstations on subnet B learning which machine is the PDC. This can happen via a broadcast, WINS or a lmhosts entry. If subnet A and subnet B are separated by a router, they may block the broadcast. Since you have no WINS, that leaves a lmhosts entry. There is a file called lmhosts.sam in WINNT\System32\drivers\etc. Rename the file to lmhosts with no extension. Then, add an entry similar to this:

102.54.94.97 PDC_NAME #PRE #DOM:domainname
