We have the following problem by a customer:
There are Windows 7 Clients connecting to a share located on a virtual Windows 7 who is running on a physical Windows Server 2012 R2 with Hyper-V.
Sometimes (at least once per week), the connection from the clients (Windows 7 64-bit) to this share is lost and its not possible to connect until the physical Server is rebooted.
There are no Errors in the EventLogs on the physical Server and virtual Windows 7.
I have tried to rearrange the Virtual Switch, but did not resolve the problem.
Any similar issues from other Servers (more than five) with same components were until now not detected.
