HYPER-V Logon as a service

Discovered today that you need to create a GPO to allow the account “NT Virtual Machine\Virtual Machines” to logon as a service.

Without this, you will discover that eventually you will not be able to start a VM.   It will give a Logon denied error message.

• Install the GPMC on a Hyper-V server
• Create or modify an existing GPO to include the above account in the LOGON AS A Service policy
• Run GPUPDATE /FORCE on all Hyper-V servers.
