When I try to convert a physical ISA/TMG machine to virtual using SCVMM, i keep getting an error in the Collect machine configuration step ('Scan Now' button):
VMM is unable to complete the request. The connection to the agent MACHINE_NAME was lost.
Ensure that the computer MACHINE_NAME exists on the network, WMI service and the agent are installed and running and that a firewall is not blocking HTTP and WMI traffic.
ID: 3157 Details: The RPC server is unavailable (0x800706BA)
Firewall rules allow for RPC traffic from the SCVMM machine to ISA/TMG machine.
