SQL 7.0 on an NT Server. Approximately 70 simultaneous connections.

All users have only Client Network Utility installed. All configured to connect via Named Pipes.

Workstations are equivalent in power.

Some users run very slow opening and accessing the SQL Server while other users have quick access time.

Could anyone give some advice on trouble-shooting/analyzing these connections? Any possible reasons for this difference?

I really appreciate the help!
