(0x80004005) Error ?????

I'm using an access 2000 database with iis 5.0 in win 2k prof.

The asp page is connecting to the DB with an odbc connection.
The following error occurs:

Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
/EuroC/login.asp, line 679

I have tested the ODBC connection from a normal VB app. and it works fine.
Also before i upgraded from NT4.0 and iis4.0 to win2k prof. , the ASP application worked fine.

If anyone has any ideas on what this please get back to me as this is fairly urgent.
Thanks
Dave

Try using a DSN-less connection with an OLEDB provider. Even if it doesn't directly solve your problem you should get a little better performance.
