I am running VMM 2012 SP1 with Rollup 2. I just added a host that had not been added before. The host is running Windows Server 2008 R2 SP1. The agent installed successfully and the status of the host shows all the correct config (ie. memory, disk space, etc). However, it doesn't show that any VM's are running on it. However, there are four existing VM's running on this host. If I open Hyper-V Manager onthe host, it shows 4 VM's running. The Windows firewall for the Domain is turned off so that's no the problem.
Anyone have any ideas?
