If the product references the "PDC" then chances are VERY
GOOD it is a NetBIOS (rather than DNS) application.

NetBIOS isn't going to work across routers (or your switch
as you say) with just broadcasts.

DCDiag will NOT report a NetBIOS error -- only DNS and
other AD problems.

Chances are very high that you need a WINS server and to
configure ALL machines (including DCs) as WINS clients.

The real "clients" so they can find the important servers and
other machines, and the "servers" so they will REGISTER
themselves.
