SQL Server users lockup every hour

Hi.

I have a peculiar problem, I think, in our SQL server database that runs our accounting and order entry applications. We have about 80 users who are attached to the server through an ODBC link (named pipes) with users running either Win2K or XP clients.

Every once in a while, sometimes weekly, we get a situation that occurs that causes all users to freeze in their application. The Server itself will still be running fine, just the clients using the SQL server applications get locked up. If I simply stop and immediately re-start the SQL server, the clients will unfreeze after restarting the application they were in (an Access based front end with ODBC linkage to the SQL server).

The odd thing is that after I do the restart (using the SQL services using the SQL Server Service Manager), it will freeze our users again almost exactly 1 hour later (about 1 hour and 3-5 minutes). I have watched this happen four successive hours. The only way to fix the problem is to restart the actual Windows 2000 Server. The problem goes away for maybe a week, sometimes several weeks, then resurfaces again with the same scenario. I don't see anything in the Server log or SQL Server log that flags anything, but maybe I am just missing something obvious.

Any ideas? Thanks.

Thanks. There is nothing that runs on a re-ocurring basis. Users are just creating new invoices or creating new orders in the SQL database. Of course someone could be running a report, but it would never happen on an hourly basis. I will try your suggestions. Thank you!
