One of our Windows VPS customers received following error while connecting to MS SQL server.
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)
Upon checking the error message at event logs, we came to know that the connection on MS SQL server was already made and new connections were being rejected. To fix connection restrictions, we set user connection limit to unlimited as follows.
- Open command prompt with Administrator privileges and issue following commands.
exec sp_configure 'user connections', 0
- After issuing above commands restart MS SQL service.
