More than often, deploying SCVMM server and managing VM hosts require coordination with your network admins. One of the frequently asked questions is "What ports should I ask my network guy to open for me in order to allow SCVMM server to talk to the hosts?". For a tightly controlled enterprise data center, this question will come up for sure. By default, everything is blocked. Ports are only open (or exempted) per request and with good justifications.
Other times when a host failed to be added or the host agent goes into a "Not Responding" state, if you cannot afford to turn off the firewall, you might be scratching your head to try figuring out what port needs to be open and what needs not.
So, to make our SCVMM admin's job easier, here is the list of TCP/IP ports SCVMM needs to talk to various system components:
Hope this helps.
