We are running Windows NT Server 4.0 for the Server OS and the workstations are running Win9X. Some workstations are Win95 and some are Win98. We log in with a user name, a password and a domain. We communicate over TCP/IP. It must be related to the networking client we are using (Client for Microsoft Networks). If I run Visual FoxPro 6 the SYS(0) returns the machine name and login user name as I would have liked from FPW. I think that's because VFP is 32-bit. I haven't learned VFP enough yet to port my application so I am trying to see what my options are with FPW.

Thank you for your suggestions.
