Access Linked Server: Works In SQL2000 But Not SQL2005

I am runing Windows 2003 which has both SQL2000 and SQL2005.

The following works in 2000 but not 20005





Code Snippet
DECLARE @sql nvarchar(4000)
set @sql = 'sp_addlinkedserver @server = N''dbAccessPO'',
@provider = N''Microsoft.Jet.OLEDB.4.0'',
@srvproduct = N''OLE DB Provider for Jet'',
@datasrc = N''C:Temppopts.mdb'''
exec sp_executesql @sql
set @sql = 'sp_addlinkedsrvlogin ''dbAccessPO'', FALSE, ''sa'', ''Admin'', NULL'
exec sp_executesql @sql




Running this:




Code Snippetselect * from dbAccessPO...MyTable




Produces this error:




Code Snippet
OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "dbAccessPO" returned message "Unspecified error".
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "dbAccessPO".





I login using sa for both instances.

I could really use your help.

Thanks.
