After we installed our weekly McAfee VirusScan patch last week the SCOM agents were no longer to communicate with the Operations Manager. The error we keep getting is:
The OpsMgrConnector cound not connect to (SERVERNAME):5723. The error code is 10061L(No connection could be made because the target machine actively refused it.). Please verify there is network connectivity, the server is running and has registered it's listening port, and there are no firewalls blocking traffic to the destination.
We have verified the connectivity and the server is running but the agents are still not able to communicate with the Ops Manager.
No one has any thoughts on this? We are running Windows Server 2008 R2 Enterprise x64 Edition SP1 on our servers and System Center Operations Manager 2007 R2.
We've tried a couple different work arounds but neither succeeded:
I certainly do not imply any disrespect with your issue but I think you need to be posting in the Business Community for assistance.

Not an issue I'm familiar with sorry.
Network communication issues, at least with regard to VirusScan Enterprise if that is observed to be the catalyst or cause, bring focus immediately to our mini-firewall filter driver (mfewfpk.sys and mfetdik2.sys).
If you have a reproducible test case, you can confirm the involvement of our code by renaming the driver(s) and rebooting - then test.
However, as a test it offers no help toward finding root cause, it's simply a litmus test to verify our code is part of the equation.
