Hi Friends.,

We are facing the following problem continuously since last week.

We have services, which pull data from other databases(SQL Server 2008 R2 and SQL Server 2000) to Our SQL Server Database (
SQL Server 2008 R2(RTM)). This services are running more than 1 year without any problem. 

But, Since last week,

SQL Server doesn't respond properly. We are not able to login SQL Server and getting the following error:

<b>Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding. (Microsoft SQL Server, Error: -2)</b>

We can able to login after restart the server.

Since we have checked the event viewer, we found that the following error were continuously logged.

SQL Server Assertion: File: <qxcntxt.cpp>, line=956 Failed Assertion = '!"No exceptions should be raised by this code"'. This error may be timing-related. If the error persists after rerunning the statement, use DBCC CHECKDB to check the database for structural integrity, or restart the server to ensure in-memory data structures are not corrupted.

The application which uses the SQL Server has a log file which shows the following error:
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 - The wait operation timed out.)

What is the wrong with SQL Server???</qxcntxt.cpp>

Though i am no expert in this area, server configuration.
Is it might be because of one server clock is not running properly, because of what SSL hand shaking might fail.
