This has been shared for administrative purposes. The permissions cannot be set.
Windows 2000 maintains default administrative shares that cannot be removed permanently. The shares have a dollar sign ($) suffix, are invisible to network browsing, and are only accessible to accounts with administrator privileges on the particular machine. You can disable these shares, but only for the current session. When you restart Windows 2000, the shares will be re-enabled. You cannot change the permissions on these shares anytime.
No user action is needed.
