I'm trying to figure out which ports I have to open on my MSSQL-Server to let the SCOM (System center operations manager) connect successfully.

I've tried:

disable the domain network firewall -> SCOM successfully connect.

new rule allow TCP inbound ports 1-65535 -> SCOM successfully connect.

If I just enable port 1433,1434 no connection can be established (from Technet.microsoft)

Which ports do I have to open?

I'm using SCOM 2012 with MSSQL 2014 on win Server 2012R2

  • Have you tried to telnet port 1433 to verify that your firewall rule is set up correctly? Are you sure no-one changed the default ports? – Reaces Jan 28 '15 at 13:14
  • ive installed telnet server and client. telnet does not work using command telnet msql-server 1433. neither does when both firewalls are disabled. neither does on default port 23. i just installed mssql as well as scom, with all default values. im using a named instance on mssql server – Joel Jan 28 '15 at 13:28
  • Are you currently trying to install SCOM? Or are you talking about having a SCOM agent on the SQL server connect back to the SCOM Management Server? – Jacob Jan 30 '15 at 7:01
  • Im installing SCOM, in the installation process i disabled the firewall. success. then enabled firewall, set the port rules, started OpearionsManager (running on another virtual machine), and it said: "connection to server" forever. – Joel Jan 30 '15 at 7:50

Since 2008, SQL Server answers on dynamic ports by default. You can set static ports in SQL Server Configuration Manager.

To turn Dynamic Ports off, erase the 0 that appears on the right side, above the port number (in this case, 1433).

Once you have static ports, you'll need to enable access to 1433 TCP and 1434 UDP.

  • i did configure it as you said, restarted the mssql-server. no success. do i have to "enable" IP1 & IP2, because now it is set to enabled - no? – Joel Jan 30 '15 at 7:48
  • the connetion cannot be establish. The Operations Manger Console says "connection to Server", until i disable the Firewall at my MSSQLserver. – Joel Jan 30 '15 at 14:44

I had to configure the static ports for IP1, IP2, IPAll, Erase the 0 at Dynamic Ports and set TCP Ports to 1433, however, Im using a named instance.

also open firewall ports

Once you have static ports, you'll need to enable access to 1433 TCP and 1434 UDP. (Katherine Villyard)
