Question : Since upgrading to SQL 2008 linked Access Tables/Queries Very Slow

We run a drill hole database that has a SQL server backend. I have linked the SQL tables to Access 2007 DB and made a number of queries that I use via ODBC connection in GIS software (MapInfo). This has worked very quickly in the past but have recently upgraded to SQL Server 2008 and the queries in Access have slowed down to snails pace. When I refresh a table in MapInfo it takes up to 30mins when in the past it would take less than a minute. Opening the linked tables in Access is still very fast but the quieries have become unworkably slow. Any ideas?

update the statistics of your database objects. and then try.
UPDATE STATISTICS TableName.

if you have indexes on table rebuild it.

updating statistics and rebuilding index could be time consuming for large tables and indexes so be careful when you do it.
