I ran into a server having a large problem on modifying as well as creating VM’s.
The matter was exacerbated by the reality that the VM’s was running out of space as well as all were “saved” are offline.
I searched and investigated in lots of places but still I couldn’t make or edit any existing VM’s!
The error message is:
The server encountered an error while configuring network on ——– Failed to add device ‘Microsoft Synthetic Ethernet Port’.
I need to solve this. Please help me.
In this case the box was running AVG and by inserting exclusion on the virtual device directory the, since I have heard of same issues with some other AV applications and moreover MS Forefront sometimes causing the similar issues.
