Windows restore and Share permissions

I'd to recently do a tape restore of the D drive on one of our machines and the restore worked fine. But the shares were not enabled immediately. After a bit of reading, I figured out this nice thing that Windows stores the shares and security permissions here in the registry

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares

All you need to do is restart the server service.
If you are in any case gonna reinstall the server, etc, you can backup this registry (done automatically if u do a system state backup) to a .reg fiel and restore once you're reinstalled the server.
