Remote access to SQL Server 2008 R2 on Windows Server 2012 R2? I have SQL Server 2008 R2 (named instance) on a Windows Server 2012 R2:


Enabled remote access to SQL Server 
Enabled shared memory &amp; TCP/IP protocols &amp; named pipes for the SQL Server instance. 
Created a firewall rule for TCP Port 1433
Created a firewall rule for UDP Port 1434
Created a firewall rule for SQLBrowser.exe
Created a firewall rule for SQLservr.exe
Ensured SQL Browser &amp; SQL Server are running


I'm able to remotely access SQL Server (ip\instance name,port number) but can't access with (ip\instance name).

I tried with turning off firewall, but the problem was not resolved.

How can I fix it?
It is a known issue with Sql Server 2008. Happens also in SSAS.
Search for Microsoft fix/ or ask support for it (fix applies on the OS site and not the DB site).
