2008 R2 VMs on 2012 R2 Hosts show unidentified networks or non-domain networks(ie network #) RRS feed

  • Question

  • Starting last week, I have 3 2008 VMs on a 2012R2 Host that will loose its connection to our domain ( ie cant ping or RDP).  All 3 servers have static IP address.  Now I can  make a change to the virtual adapter and reboot and then reassign the static IP and the server will connect to the domain network and will be fine until the next morning.

    These servers were migrated via SCVMM about a month ago and have been fine tilll a week ago.

    There is a fourth VM on the Host that has not been affected at all.

    I have made changed to the Host virtual network switch with no affect on this maddening behavior.

    Thanks in advance!
