SQL server setup problem

I'm trying to install Web Wiz Forums 7.5 with MS SQL 2000 but I keep getting an error when trying to execute the "msSQL_server_setup.asp"-step.

I've tried all things posted already in this forum and information available on the internet.

Situation:

• Microsoft Windows 2000 5.00.2195 Service Pack 4
• Microsoft SQL Server 8.00.194

Problem:

Executing msSQL_server_setup.asp and logging in gives the error: "Error Connecting to database on SQL Server" with some advices how to solve the problem.

Already tried/did:

• Installed MDAC 2.8
• Created an empty database and a user and given all required permissions
• Quoted the "On Error Resume Next" line in "msSQL_server_setup.asp" which then gives the following error:

Server object error 'ASP 0177 : 8007007e'

Server.CreateObject Failed

/kennisbank/msSQL_server_setup.asp, line 180

8007007e

• Double checked the login information (Login in with the Microsoft SQL Server Query Analyzer does work)
• Manually registered msjetoledb40.dll and oledb32.dll

Somehow the "ADODB.Connection"-object can't be created (in the line "Set adoCon = Server.CreateObject("ADODB.Connection")")

I really don't have a clue what to try next or what the problem is. Help and suggesions are appreciated!
