[Ryan0827]

We are experiencing an interment exception when querying SQL Server over our VPN a WinForms application that uses typed table adapters to get and update data on a SQL Server database. The exception below is thrown at completely random times, during costly queries, during tiny queries, when several users are accessing the database during the day, or even when it's just me at 1:00am. The same error happens intermittently in SQL Server Management Studio. I can't seem to come up with a method to narrow down the issue. Would anyone know how to troubleshoot this and/or fix it?

I've heard this may be a network socket issue and Winsock is throwing the error, but SQL Server is reporting it.

See the end of this message for details on invoking

just-in-time (JIT) debugging instead of this dialog box.
