While I try to connect to SQL Server, I am getting the following error:

A connection was successfully established with the server, but then an error occurred during the login process. (provider: TCP Provider, error: 0 - An established connection was aborted by the software in your host machine.) (Microsoft SQL Server, Error: 10053)

How can this be solved? What may be the cause of this issue?

  • Can you connect at all? Even locally on the server? ANd what does the Windows event log say? – gbn Jul 3 '13 at 6:50

There are several causes for this. The ones I know of (at least)

Have you ever connected? Changed any settings? Have a backup of master? What other errors are there in the event log?

Anyhow, restart SQL Server with the -f option and ensure the the 2 settings above are sensible.

  • Your reply is almost correct. Restarted that particular instance and I could now connect to the same..Thanks for that.. :) – Vysakh Jul 3 '13 at 7:34
