The VMRC client is only one of several possible ways you could connect to a virtual machine. My personal favorite way to do this is just to set up a remote desktop client (RDC) connection, which is built into Windows and works as transparently with virtual servers as it does with a real remote computer. VMRC uses its own protocol which is deliberately distinct from RDC, and which has been engineered to allow multiple users to connect to the same virtual machine transparently. If you're only using one connection at a time to administer virtual machines, use RDC instead; it'll be a little smoother.
