Prevent the power users from mapping drives

Are you discovering that power users are mapping drives they shouldn't? Here's how to prevent them from doing so.

Note: This involves registry editing, so be sure you have a verified backup before you begin.

1. Using Regedit32, navigate to HKEY_USERS\.DEFAULT\Software\Microsoft\
   WindowsNT\CurrentVersion\Network\Persistent Connections.
2. Double-click SaveConnections, a type REG_SZ entry, and change the value to No.

The Persistent Connections subkey stores data about the most recent connections to your network drives. These values are all of type REG_SZ. The UNC path of the drives most recently connected to your computer will be displayed with letters a-j. Up to 10 drives may be stored in the registry information. However, drive letters connected via the NET USE and/or the SUBST commands do not appear in this registry entry.
