Question : Local registry hack vs. Group policy -Who wins?

Environment-W2K pro client and W2003 domain controller.

There is a group policy in server 2003 that allows admins to hide the c drive (or other drives for that matter I think) for a specific domain user/users.

There is also a registry hack that can be done on W2K pro clients HKLM\software\microsoft\windows\current version\policies\explorer\NoDrives (key) = 4.

The hack above will hide the c drive. However if I made this hack value 8 instead, it is supposed to hide D.

My question is, if the hack value is 8, and I have the group policy in place to hide C only, when the user logs in, what drive or drive will be hidden and why?

Answer : Local registry hack vs. Group policy -Who wins?

If the GPO is set to modify this key, then the GPO will "win".  All GPO is, is the application of various registry settings on computer or user log-on (well, it does offer more, such as scripts and software installation, but essentially it can modify any part of the registry).  It will override any registry settings already in place, but only if that policy is defined.

If the GPO is modifying a different key, then BOTH drives will be hidden.  I would guess that GPO is in fact changing the same key though, and GPO will override any local settings in a domain configuration.
