Can't make ADOConnection to Oracle 8i

Hello,

I have C++Builder 6, Windows 2000 and Oracle 8i 8.1.5.

I have an TADOConnection which uses a udl file which points to an 8i 
database.  The udl file test connection tests fine.  When I try to set 
the ADOConnection property Connected to true at runtime I get an 
EOLException with message "Catastrophic failure".  If I set the 
Connected property to true at design time the connection opens fine.

All my Oracle apps connect to the database fine.

I have Delphi 6 on the same machine and the behavior is the same.  I've 
reinstalled Delphi twice and BCB once.

The strangest thing about this is the design time works fine, but I 
can't make the runtime work at all.  And I've tried building the 
connection stringin BCB and changing the OLEDB driver from Oracle to 
ODBC.  Nothing works.

Can someone please give me some ideas.  Or does anyone else have bad 
experience with Windows 2000.

Thanks
