SCOM Agent requirements and firewall ports…
From time to time I find myself in scenarios where I do not remember of all requirements that are needed to install a certain piece of software. This happens because each new product has new requirements. The new software is not the issue, the issue is that we’re seeing lots and lots of new software coming and going and reviewed all the time, those changes come with new requirements, and those new requirements for Vers.xxx of the Product yyy.y are not equal to previous versions of the same product. Multiply this by the number of different existing software versions within your company computers and this may become messy after a while…
So, what can we do? Bog it…
For this post I’ll note (for me and for yourself) the Firewall ports that are needed by OpsMgr Agent Push process. Additionally I’ll also post some useful links that may clarify some doubts when doing agent deployment using System Center Operations Manager.
The following table lists the OpsMgr Agent push requirements for Firewall Ports:
| Name | Port Number | Protocol |
| RPC endpoint mapper | 135 | TCP/UDP |
| RPC/DCOM High ports (Win 2K/2K3 OS) | 1024-5000 | TCP/UDP |
| RPC/DCOM High ports (Win 2K8) | 49152-65535 | TCP/UDP |
| NetBIOS name service | 137 | TCP/UDP |
| NetBIOS session service | 139 | TCP/UDP |
| SMB over IP | 445 | TCP |
| MOM Channel | 5723 | TCP/UDP |
