We have an access xp application tied to a sql 2000 backend. After moving to a clean install of windows 2003 sp1 from windows 2000 server the application slowed down noticably and the number of odbc errors increased. I have tried: - installing a 2003 server and converting to access 2003 - moving the backend to a sql 2005 server - running access in 2000 compatability mode - tuning odbc settings and connection pooling. I have not had much luck finding existing information on this problem. Any suggestions would be greatly appreciated.
