Scheduling remotet tasks
I support servers across the country and have a few processes that allow me
to execute tasks on all the servers using scheduled tasks. A script runs
through a server OU and creates a CMD file that looks like this.... (
simplified )
at \\server1 4:00 d:\utils\process.cmd
at \\server2 4:00 d:\utils\process.cmd
at \\server3 4:00 d:\utils\process.cmd
at \\server4 4:00 d:\utils\process.cmd
..
..
Executing this CMD file then schedules process.cmd to run on all servers at 4:00 AM.
There is one process in particular that I would like to have run at the same
time on all servers, but when the tasks are scheduled using the AT command
as seen above, the task runs on local time. Since my servers span the
country, several time zones are crossed.
Is there a way using AT or SCHTASKS that tasks can be scheduled to run at the same time (GMT) even though they cross time zones?
A simple "NO" answer gets you 50 points.
A "YES" and help to solve this will earn between 125 and 250 depending on the difficulty.

no, I think you will have to script custom kick off times... You can either manually organize your servers into time zone and edit the script for the proper kick off time, or device a mechanism to check the system time zone before running the AT.

This worked with a little engineering.
Using psexec like
psexec @DCList.txt \\rmtserver\rmtshare\scrip
will execute the script on all the servers, however, the process runs through the list of DCs in the text file, running the script against each server consecutively. This gets the script run on all servers, but when I have about 60 DCs in the list, and the process runs between 2-3 minutes on each server, that makes for a two to three hours time difference for the execution on the first and last servers.
...so...
I modified my script to create the CMD file....
psexec \\server1 \\rmtserver\rmtshare\scrip
psexec \\server2 \\rmtserver\rmtshare\scrip
psexec \\server3 \\rmtserver\rmtshare\scrip
..
Thanks for your help!!!

So when I execute my CMD file, the script gets remotely launched on all DCs at the same time.

FYI ... Below is a script which I received to this question from a news group. It uses a method where you determine the time zone offset for each server and adjust the execution time for the AT command. This is very interesting and something I will spend some time working with too.
Save the following as sGMT.bat:
@echo off
if {%4}=={} @echo Syntax: Call sGMT \\Server GMT_Hour_2_Schedule GMT_Minute_2_Schedule FQFN&goto :EOF
setlocal
set key=%1\HKLM\System\Current
for /f "Tokens=3" %%a in ('reg query %key% /V ActiveTimeBias^|FIND "REG_DWORD"') do (
set /a off=%%a
)
if %off% GEQ 0 goto pos
set /a off=0 - %off%
set /a oh=%off% / 60
set /a om=%off% - (%oh% * 60)
set /a oh=24 - %oh%
set /a sh=%2 + %oh%
set /a sm=%3 + %om%
if %om% NEQ 0 set /a sh=%sh% - 1
goto :OK
:pos
set /a oh=%off% / 60
set /a om=%off% - (%oh% * 60)
set /a sh=%2 + %oh%
set /a sm=%3 + %om%
:OK
if %sm% LSS 10 set sm=0%sm%
AT %1 %sh%:%sm% %4
Then, in your batch
call sGMT \\server1 4 0 d:\utils\process.cmd
