I know this has been asked before and I have tried the previous solutions and still have an issue.
I have installed SQL Express 2012 on a server which also has an instance of SQL Server 2005 and possibly an Express 2008 instance as well.
I can connect to the instance SERVERNAME\SQLEXPRESS locally, however am unable to connect remotely.
I have tried the following:
Enabled remote connections
Configured TCPIP to port 1434 (the 2005 instance has 1433)
Allowed TCP 1434 and 1433 incoming in the firewall on the SQL Server box
Started the SQL Server Browser
Tried both Windows Authentication and Standard logins
Tried to create an ODBC connection
Nothing has had any effect. Please help!
