I don't have all environment ready for this testing but I need to get
approval and need help.

If I upgrade my SSAS 2000 with SSAS 2005. On client side we have Excel 2002
now.

My question is with SSAS2005 if I install
a) Microsoft Core XML Services (MSXML) 6.0
b) Microsoft SQL Server 2005 Analysis Service 9.0 OLE DB Provider
on client box they can still use Excel 2002 to access cubes in AS 2005 right?

Thank you - Ashok
