The server hosting the RCS has its firewall enabled. I cannot connect to it using SCS Console from client PC or from the SCCM server during SCCM Add-on installation. I know there is a small section in the manual that states:
--------------------------------
If you install the RCS on a computer that is protected by a firewall, you might receive error messages when you
try to connect to the RCS.
Solution:
You must make sure that the firewall is configured to enable the WMI to connect to the RCS. For more
information, refer to the Microsoft Developer Network:
http://msdn.microsoft.com/en-us/library/aa389286(VS.85).aspx
--------------------------------
However this doesn't help in any way. I click the link but the page talks about using VBScript? If I disable the firewall on the RCS server I can connect so it's obviously a firewall issue, the question is which port/s do I need to open? If I capture the traffic on my PC whilst trying to connect to the RCS server I see attempts to connect on port 135 except I have tried enabling the rule "Windows management Instrumentation (WMI-In)" on the server but no luck.
Any ideas?

Graham,
you need WMI -in TCP port 135 to be opened to allow SCS console to connect - otherwise you will get Timeout error in SCS console.
Make sure that you use right RCS server IP or FQDN.
+
you need to enable AD user of SCS console in RCS WMI Name Space and DCOM permissions on RCS -otherwise you will get Access Denied error message in SCS Console.
the best way is to use RCSutils.exe tool with /Permissions Add command.
See SCS User Guide section called User Permissions Required to Access the RCS (3.8 for SCS 11.1)

Thanks for your reply Dariusz,
I tried this but it doesn't seem to make any difference, I still cannot connect. However, before that I managed to discover, by process of elimination, the correct ports to open on the firewall. If I opened up tcp 135 (not the built-in rule for WMI-In) and also a port range of 50000-55000 I was able to connect from my PC and from the SCCM Add-in wizard. I would still prefer to do it the correct way. Can you advise? Should I open a support ticket?
Thanks, Graham

It is working now. I needed to enable the three rules:
- Windows Management Instrumentation (ASync-In)
- Windows Management Instrumentation (DCOM-In)
- Windows Management Instrumentation (WMI-In)
