From agent's log:
[#6] [2014-01-08 07:52:33.917 02696 warning 'App'] [,0] [NFC ERROR] NfcNewAuthdConnectionEx: Failed to connect to peer. Error: Host address lookup for server wm-vmscan1 failed: No such host is known
The source machine can't resolve "wm-vmscan1". A workaround would be to add it (along with its IP address) to the source' hosts file.
