A new server just implemented (Server 2012 std). AD role migrated from old server and have all user accounts, passwords, data.
New install of SQL 2012 and configured correctly by SQL application vendor.
We cannot get the server to listen on Port 1433. Server does listen on numerous other ports and can telnet to other ports. SQL can connect on the server via the SA login.
We have tested or done the following:
Added rules for Port 1433 in the server firewall
Added Port 1433 to SQL settings
Rules for port added to router
No issues with IIS
No other applications, antivirus or other firewall on the server
At this point we still cannot listen on the server for Port 1433 nor telnet. At this point we are at a lose for options.
