Invalid Instance Invalid Connection NT 4.0

When connecting to SQL Server using a Win NT 4.0 client I receive the messag
e:
[DBNETLIB] ConnectionOpen [Invalid Instance ()]Invalid Connection
Another Win NT 4.0 client works fine.
SQL MSDE 2000 release A installed on the server. Another SQL 2000 instance
is running (from another vendor) on the same machine. MDAC 2.7 sp1 refresh
checks out fine in component checker.
Any idea?By default MSDE 2000 SP3 only allows local connections, you have to go in
and enable MSDE to listen on TCP or Named Pipes if you wnat to allow remote
connectivity.
