Connection Refused - SAP GUI 6.40 & NW2004s

Hi All,

I've installed NW Sneak Preview Java Slim Edition on Windows 2000 Professional with SQL Server 2000. I also installed the latest SAP GUI for Windows 6.40. The install went fine for both but when I try to log in via the GUI logon pad I get a "Connection Refused" error from the server.

I've tried using the IP address, the computer name and "localhost" (which the documentation shows), using a system ID of "NSP" and system number of 00.

Any clues about what is wrong here?

Thanks for your help!
