on win 2003 server domain controller

It’s working after installation, reboot and last known good config boot (space at reboot).
The on access icon tell me that on access is disabled but with process explorer it seems to be properly scanning…don’t konw on on access blocking

It seems that a new problem appears after some day of functionality:
on the 2003 server i find the system locked and cdrom that runs without any disk inside.
Ought to reboot with last known valid configuration
