Seen when trying to navigate to \\computer-name from windows7 where the target is an XP virtual machine, under vmware workstation. Both machines are members of an Active Directory domain. The g'oracle indicates this message has to do with AD replication failure and similar. Most of the hits have to with server configuration though, not workstations.
Rejoining the workstation to the domain made the error message go away, but did not accomplish the original goal: accessing the vm file system from the host while running.
That's curious: the guest vm in NAT network mode can authenticate via AD, even though it's ip is local to the host (192....etc).
In any case the fix is to access the vm via ip address (\\192.168...) or change the network mode to bridged.
