When adding a Windows Server 2008 / EMC Symmetrix Cluster (Geo-cluster) as a host to SCVMM 2008, you may get error: Code: 1612 Problem: The connection to the Virtual Machine Manager server localhost was lost. To resolve, first test to verify that this’s in fact your issue. To do this, on both of your Windows Server 2008 / EMC Symmetrix Cluster "nodes", run the following command: C:\cluster node -priv
If you get an output that’s anything other than nothing, you’re likely experiencing behavior that requires KB958807 and it’ll cause a crash in Windows Server 2008. To resolve, apply KB95887 to all your nodes in the Windows Server 2008 / EMC Symmetrix Cluster. The requirement for this hotfix is that it must be applied to Windows Server 2008 RTM SP1.
