Remote Connection to SQL Server 2012 Standard Edition port 1433

Question

I have a Windows Server 2008 R2 running SQL Server 2012 Standard Edition and:

• Allow remote connection to this server (in SQL Server Management Studio)

• TCP/IP Enable and configured IPserver and 1433 port (on SQL Server Network Condiguration -> Protocol for...)

• Named Pipes Enable (on SQL Server Network Condiguration -> Protocol for...)

• Shared Memory Enable (on SQL Server Network Condiguration -> Protocol for...)

• Firewall Off

When I run telnet localhost 1433 on the server - connect perfect. But if I run telnet IPSserver 1433 or telnet DomainNameServer 1433 - not connect

Something else netstat -a display:

0.0.0.0:1433   NameServer:0  LISTENING
[::]:1433      NameServer:0  LISTENING

Any ideas?

Answer 1

You probably have the Firewall turned on, so you have to create an exception to TCP/1433.

Be aware that if you have multiple instances you must also create an exception for UDP/1434 and check on which port the multiple instances are binding.
