WinDbg loses connection debugging over network, and target machine freeze

I found a simpler solution that worked for me in VMware, The problem is in vmware - the NAT connection has a 30 seconds timeout. This value is configurable. Go to edit -> virtual network editor -> change settings (uac prompt) -> select NAT in the list -> NAT settings -> UDP timeout. The max value is 32767, the default (for me) was 30 seconds. It completely solved my problem.

I had the similar problem and solved it by using USB to Ethernet adapter on the host machine instead of in built NIC card.

I finally solved this problem by switching the host system. In the beginning, I thought the target system was the problem, because MSDN only put the NIC debug requirement on the target system. It appears that there might be requirements placed the host system as well.

New host system: Desktop (Identical to target system)

• OS: Windows 8.1 Enterprise Evaluation x64
• NIC: VEN_10EC&DEV_8168

Previous host system: Laptop

• OS: Windows 8.1 Pro x64
• NIC: VEN_8086&DEV_1502

NOTE: I don't really know the root cause. Both NICs are on the Supported Ethernet NICs list, I used the same WinDbg version that came with the WDK, and all systems are on the same switch.
