I’m running Windows 2008 R2 as a Hyper-V host. I have 5 VMs running on this host, all Win 2800 R2. On one of the hosts, I’m no longer able to modify the network configuration since patching this weekend. When I go into Network -> Properties it shows the server is on a domain and the access type is Internet, but the Connections field is blank, where on all of my other VMs it says “Local Area Connection” and it’s a hyper link to modify the network adapter properties. See below:
Also, from this server I cannot access shares on other file servers and the shares on this server cannot be reached. I can sign into the computer from both the Hyper-V host and from a remote console and it does reply to a ping command by the VM server's name.
I have rebooted the servers, I have removed the virtual network card and reapplied but nothing has helped.
The patches that were applied were KB3212642, KB3212646, KB3205402 (2 January security and quality rollups and 1 December .NET rollup packages) and KB3045316, the SQL 2008 SP3. These same patches were applied to about 20 other servers, none had issues.
Any ideas or suggestions?
