Hi We have an application running on W Server 2008 R2, that uses Access MDB 2003. We encounter often the problem described in the title. Application freezes, and the system becomes slow... Sometime after 15 minutes it succeeds to complete the query. Sometimes no. The same application doesn't have any problem running on R1 or W Server 2003 OS. Is there a patch or something that can we do to solve the problem? Best Regards

Hello, please post an unedited ipconfig /all from the server and a problem client.
