I have a SQL Server 2008 R2 Developer edition set up on a Windows Server 2008 R2 edition and although I was able to get into the database locally via SQL Server Management Studio (using my server name\MSSQLSERVER), I was unable to get in there remotely (using IP\MSSQLSERVER).
I have turned off the firewall for Windows (no other firewall installed) and turned on all 4 protocols for SQL Server (Shared Memory, Named Pipes, TCP/IP and VIA) and has turned on every single service in the SQL Server Management Studio with no luck.
Could you please help me?
Many thanks in advance!
Problem fixed after reinstall the whole system and open port 1433 for TCP connections.
