Security

the best way to set the time is durning a logon script see MS tech net Q131715 for instructions on how to set up server and clients, if you don't have tech net email me and I'll send you the doc. for the other stuff use poledit to restrict access.
hope this helps

the net command line is
Net time \\servername /set /yes
as for all the other stuff Poledit (just do asearch on the server).

The net time command should work from a logon script with no modification given that the script runs in the "System" context. That is usually the best place to run it.

As for the rest they are standard settings available in the Zero Admin Kit as.adm files. I can't recall, you may need to edit the .adm to get exactly the "hide drive" you are looking for, but it says right inside the .adm how to do that.

There is a .adm on the www.winntmag.com site that lets you specify screen saver!

The answer to setting your Privileges is to the User Manager, Policies Menu, User Rights, and scroll down to Change System Clock, by default only Administrators (and Server Operators) can change the setting, so ADD the Users Group, or Domain Users, or even Everyone, and then the Logon scripts will run fine.

There may also be a utility in the Resource Kit called Timeserv see TechNet Q131715
which offers an alternative strategy to Time Synchronisation.

In addition, I used a small utility called TARDIS (probably a trademark infringement), but it worked very well on NT (wkstn & server) and Windows 95. I used the Proxy server to collect the time from known good Internet sources and pointed all the clients at the internal server interface.
