#Windows 7 stuck on identifying network windows#

Changing the GPOВ (GPO -> Windows Settings -> Security Settings -> Network List Manager Policies ).Removing all VLANs - no VLANs physical or virtual.Removing virtual switch,В 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 andВ adding back in again.I tried bunch of different things but none sticking (temporarilyВ feels like itВ problem is fixed but then it comes back in hours or days).В 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 theВ machine,Дisable andВ re-enable the NIC - and this is aВ manual intervention not a solution. What makes it frustrating it cannot identify the network and stays inВ 'Identifying' mode.

Make sense that access is denied whileВ server is evaluating the network. Recently (afterВ upgrading AD host fromВ Windows 2012 toВ Windows 2012/R2, but not sure if it related)В 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 onВ Windows 2012 that has been recently upgraded to Windows 2012 R2.В 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.
