The last week I have noticed that Network and Sharing Center in my guest machine (Windows Server 2012 R2 Essentials) is announcing that it has no internet access. Since I'm able to run MS Update it seems to have connectivity though, so I don't really get it (!?!)
The DNS on this machine has 8.8.8.8 and 8.8.4.4 configured as forwarders. I read something about recent issues with these DNS servers.. Could that be the source to my problem?
* Host is running Windows Server 2012 R2 with no issues (as far as I can tell).
