I can no longer connect My EXCEL spreadsheet Office 2003
to Analysis Server/SQL Server 2000 .
----------
Error Message:
Open Connection failed, Unable to open connection, Unspecified eror.
-------------------------------------------------------------------
I has worked OK for a long time but suddenly not.

I have tried to reinstall Office, MDAC 8.0 and PTSLite file from SQL server
servicepack 3
but nothing works.

Do I really need to reinstall windows and all programs from the start??,
my colleagues do not experience these problems.
