ServerA and ServerB are the physical nodes, ServerF and ServerG\Inst2 are the default and named instances respectively. From last few days we have been receiving following error quite frequently in our SQL error logs.Please advise.

Just googled after the error and found this connect item

It talks about 4014 errors and says to check if the errors are occurring with the same client or not. If yes, then check for NIC issues on the client, if no, then check the server.

Following query should give information on connectivity issues of this kind :



SELECT * FROM sys.dm_os_ring_buffers where ring_buffer_type='RING_BUFFER_CONNECTIVITY'

I had also gone through the same link but setting up the trace is a challenge in our environment as client is not ready to make any changes on the production server. Is there any other alternative way of troubleshooting this error.

Have you tried the query that @WilliamD mentions? This is provided in the connect post after information of the trace.

If the client isn't prepared to let you troubleshoot the problem, how can you help them?

I would make sure that all patches are installed for O/S, SQL Server, NIC Drivers etc.

You don't have to run the trace to begin with, but at least make sure these things are covered. You can tell if the error is happening to one client or multiple clients, this should point you in the right direction.

I had run query mentioned above but the client details are not logged in the record column for error 4014. I had investigated about OS patches and drivers' update and they are up to date. I had also inquired from clients about errors, if any, logged in their application logs. They updated that no issues have been experienced from application end so far. Please advice any other way of troubleshooting.

run the trace! Tell client that it is the next logical step, quoting the connect entry with official MS answer. If they don't want to, then you are stuck. I would double-check patch levels and drivers if I were you.
