I'm trying to create a new Virtual Server on a Hyper-V Server 2008 in an environment without a domain. One of the Virtual Servers that I create will be an Active Directory server. I am trying to connect to the Hyper-V server from a Vista client. When I add the server to the Hyper-V Manager I get an error saying "Cannot connect to the RPC service on computer 'XXX.XXX.XXX.XXX'. Make sure RPC service is running."
