Isolated LAN multiple workstations time sync issue

[Guest]

We have an isolated (no links to the outside world) LAN with 25 Win2k WS for
a security control room. All machines run a scheduled task with this .bat
file after every 2 hours:

net time //Supervisor \set /y
exit

None of the workstations remain in sync after a few minutes. I have tried
the following

1. Restart all machines
2. Change sync time to 5 minutes
3. Set time zones/times to Saudi(thats where I am) standard time on all
machines

Nothing seems to work; some one suggested a virus as the culprit. Updated
Virus scans gave negative on viruses.And all machines have SP4 with all sorts
of patches on them.

For starters you should determine if the falling out of sync
is a local problem or if it is caused by some central
interference. Synchronise all machines, then disconnect one
of them from the network and check if it keeps its time or
not. If it keeps its time then it obviously synchronises itself to
a time source on the LAN while networked. Find out which
one! If it does not keep its time then there is something wrong
with its hardware clock or with Windows.

By the way, I cannot see how your command

net time //Supervisor \set /y can work. Did you perhaps mean
net time \\Supervisor \set /y

Actually it probably should have been;

net time \\Supervisor /set /y

That was a typo this is what I used:
net time \\Supervisor \set /y
I still have to try Pegasus suggestion

 

[Dave Patrick]

That can't possibly work.

To clarify;

That was a typo this is what I used:
net time \\Supervisor \set /y

The above can't possibly work.
