+All Windows NT based OS (NT, 2000, XP Pro), are configured by default
+to share the entire C drive as C$. This is a special share used for
+various administration functions, one of which is to grant access to backup
+operators. All you need to do is create a new domain user, specifically
+for backup. Then add the new backup user to the built in "Backup
+Operators" group. You now have backup capability for any directory on
+any computer in the domain in one easy step. This avoids using
+administrator accounts and only grants permission to do exactly what you
+want for the given user, i.e.: backup.
+Also, for additional security, you may wish to deny the ability for this
+user to logon to computers in the default domain policy.
