There is something obvious that I am missing or its a new feature/bug? Temporarily I changed the definition of Identifying network from "public" to "private" but that's not how I want to keep it (security!!).Īny suggestions? How do I make NIC identify the network and get out of this
#MICROSOFT HOSTED NETWORK ADAPTER IDENTIFYING WINDOWS#
This behavior is more prevalent on Windows 2012/R2 machines than on Windows 2008 hosts. Re-validated Windows 2012 R2 based cluster configuration.Tried different suggestions that I found on internet (but they are mostly related to time prior to Windows 2012).Cleaning up (uninstalling) dead (old) NICs hidden in host device manager on VMs.Changing the GPO (GPO -> Windows Settings -> Security Settings -> Network List Manager Policies ).Removing all VLANs - no VLANs physical or virtual.Removing virtual switch, re-creating and attaching the NICs to new virtual switch.
disabling VMQ (Virtual Machine Queue) and twiddling NIC settings (physical network is attached to a 1 GB Dell Layer 3 Switch). Removing the vNIC and adding back in again. I tried bunch of different things but none sticking (temporarily feels like it problem is fixed but then it comes back in hours or days). I have not experience this issue on desktops connecting to the same network over wired or WiFi connection. One workaround I found is to use Hyper-V console logon to the machine,ĭisable and re-enable the NIC - and this is a manual intervention not a solution. What makes it frustrating it cannot identify the network and stays in "Identifying" mode. Make sense that access is denied while server is evaluating the network. Recently (after upgrading AD host from Windows 2012 to Windows 2012/R2, but not sure if it related) servers are getting stuck on networking and network getting stuck on Identifying. This TMG host is default gateway for all internal assets. Its a single subnet private class C network with a dual NIC TMG host providing connectivity to internet. AD is hosted on Windows 2012 that has been recently upgraded to Windows 2012 R2. All computers All server assets are virtualized including DNS, AD and DHCP and running as guest VMs. I have a two node Windows 2012 R2 cluster hosting Hyper-V guests.
