SQL Enterprise Manager problems

I have installed SQL server 7.0 SP1 on a server (no problems). I have then installed the client tools on a Windows 2000 workstation. When I try to connect to a database on the server, I don’t face any problem but, as soon as I try to get the data from the database, I get a message : The specified module could not be found.
I suspect that there may be an inconsistency between NT libraries/drivers and Win2K ?
This is a very urgent request…
Many thanks for your help and support.
