Whilst trying to add a Server 2012 Hyper-V host into System Center Virtual Machine Manager 2012 SP1 recently I was receiving the error 414 “Agent installation could not access the ADMIN$ share on server abc123.fqdn.com.
Checking the ADMIN$ share from explorer revealed that I was prompted for connection credentials but my Domain Admin account still wasn’t able to connect. I RDP’d onto the Server 2012 Hyper-V host and tried the ADMIN$ using the UNC abc123ADMIN$. This worked leading to the direction of Riverbed which the customer is using for WAN optimisation.
Adding in a Riverbed exclusion rule and the connection to the ADMIN$ is now possible from the SCVMM server and I can now add it into SCVMM. Riverbed currently doesn’t support SMB 3 which Server 2012 uses.
