Hyper-V guest loosed access to external network
I currently run a Windows Server 2012 R2 with the Hyper-V role installed. I have 3 guest VM's running Server 2012 R2. I have 3 network adapters teamed using NIC teaming but only one of the guest looses external network connectivity. I still can communicate between the guests but cant get outside the virtual switch. The only way to fix this is to remove a Nic from the NIC team and create a standalone virtual switch. After changing the guest vm to the new virtual switch it was working again just fine.
Unfortunately the same issue reappeared after about 2 weeks and the external access was no longer possible. As a workaround I created another virtual switch with the remaining NIC and it works again. This might be short lived unless i find a permanent solution. Can anybody shed some light on the issue

did you tried to remove the affected guest VM's virtual NIC and add another one again and checked after then? If not then can you check by doing so.

yes this is now the third time this happened. the fist time a restart of the host fixed the issue. the second time i removed the virtual network and re- added it. All it would achieve is take network access away from another guest vm on the same virtual network. Creating a new virtual network did fix the issue for about 2 weeks.
