Original KB number: 2927313
Starting an imported virtual machine under Hyper-V sometimes fails with an error message that states:
The security ID structure is invalid (0x80070539)
This issue is caused when a virtual machine is moved from one environment to another, and Hyper-V can't remove an invalid security ID from the virtual machine configuration as part of the import operation.
A user can reset the state of security IDs in the virtual machine configuration by adding a new, valid user ID. To do this, you'll need to:
Open an administrative PowerShell command window.
Run the following command:
Grant-VMConnectAccess -VMName "Name of VM that is not starting" -UserName "Domain and username of the current user"
The virtual machine should now be able to start successfully.
