SQL Server 2008 R2 Remote Connection issue I have installed SQL Server 2008 R2 in mixed mode, but currently issue is I can't use SQL through ip nor ip with port, even I have enabled TCP/IP and open port in firewall too.

I tried to telnet 127.0.0.1 1433 to check whether its working or not but its not connecting
I tried almost every possible things but failed in each.

How do I get this to work?
By default Sql server may not be listening for TCP/IP connections.

Did you check this stackoverflow question?

Also check start the "sql server agent" service is started.
