I've got five servers over two sites (*). They're all on the same domain, and I have local admin access on them as well as domain admin access.
Site 1 :
Machine 1 :
Physical Windows 2012 running hyper-V
Machine 2 :
Hyper-V VM running Windows 2008R2 (or indeed a win7 laptop)
Site 2:
Machine 3 :
Physical Windows 2012 running hyper-V
Machine 4 :
Hyper-V VM Windows 2012 running SCVMM
Machine 5 :
Hyper-V VM Windows 2008R2
I'm trying to get to the admin share for machine 1 in site 1 from machine 4. It doesn't work.
"Windows cannot access \\machine1\\admin$"
"Error code: 0x80004005"
Nearly all the machines can see each other's admin shares. The exceptions are :
Machine 1 from Machine 4
Machine 1 from Machine 3
Ie across site, win2012-win2012, but only one way. If one of the boxes is win2008R2, it works, and site 1 can see site 2's shares.
Does anybody have any ideas on where to look next?
(I had a look at what's going on with wireshark. The client (Machine4) is resetting the connection after the first successful ioctl response NETWORK_FILE_SYSTEM Function 0x0081. There's no obvious important difference between this packet for a successful
connection and for an unsuccessful one.
My thought was that there may be a firewall configuration change for win2012<->win2012 file sharing, but I can't see a suitable packet being sent and disappearing, only the client resetting the connection after what appears to be a perfectly normal
few packets. Port 445 is open.)
cheers,

(* ok, I've got a lot more than 5, but 5 is sufficient to demonstrate the problem :-) )
