P2V of a Windows 7 OEM Workstation

Hi,

It is requested by my manager to perform a P2V of a Windows 7 workstation running OEM license.

After the P2V, windows license is not genuine and need another license key to reactivate (We have done this part).

Then we run SYSPREP but we get a fatal error.  We just wonder whether it would be a problem if we use the VM (i.e. P2V one) and physical workstation running Windows 7 for a while (Both of them have been joined to AD) ?   Do we need to remove the physical workstation from AD as SYSPREP fails ?

Thanks
