Trouble getting port 1434 connectivity during attempted ePO install

Jump to solution

I have VMWare lab, 2 VMs, one ePO, one SQL. I receive the error, upon attempting ePO install, that port 1434 UDP cannot be connected between the ePO and SQL servers.

 

The windows firewall is configured to let all UDP and TCP ports through, bidirectionally. The IP configuration in SQL Configuration manager is set up for 1433. If I check the SQL server to see which ports are listening, I see 1433 is listening, but UDP seems not to be. (see attachment).

 

How can I force the Windows 2016 SQL server instance to listen on UDP port 1434? That seems to be the problem.

Thank you, understood. I fixed the problem, the problem was that the VMWare software had auto-changed both VMs' IP Addresses upon a recent reboot, and both servers' hosts files needed to be updated.

Oh BTW both server instances are 2016. I have done the SQL install myself. I created a DB instance in SSMS called 'Server-2016'. When I try to do the ePO install, the installer auto informs the DB name 'ePO_EPO-SERVER-2016'. The name of my ePO server is EPO-Server-2016. The installer does not auto-detect my SQL server instance, I have to manually enter it in the 'Database Server' field. I then enter 'ePO-Server-2016' for the DB name. I am using SQL Authentication. The username I am using is entered as a login in SSMS and it does have DB_creator and Public rights.

Port 1434 udp is what the sql browser service uses.  The sql browser service should be running.  You don't connect to sql on that port, you would still use your port 1433 for connection.
