1. The ITA log shows that "Machine is already allocated". The possible cause is that the full copy template is not encapsulated; therefore, the VMs created on the AD server have a same name.

2. The name of the created VM is 22-D238C8C3A1D0.
3. The name of the template VM is also 22-D238C8C3A1D0, which indicates that the template is not encapsulated.
4. Another method for checking whether a template is encapsulated is to check the value of registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\State\ImageState. If the value of ImageState is MAGE_STATE_COMPLETE, the template is successfully encapsulated; otherwise, the template is not encapsulated.
