Can't see named instance

I have a client running NT 4.0 on one of his workstations. For some reason from that machine he can't see the named Instance on the Server (MyServer\MyInstance) and therefore can't connect to the database. If I pull up a list of available servers, the Server comes up on the list, just not the named instance. ANy ideas on what might be causing this?Old version of MDAC. Apply the latest supported MDAC for NT 4.0 and the
client can connect. Alternatively, you can create an alias on the client
that includes the port number and connect via it.
