Automate changing password for scheduled tasks on multiple servers

[Marc]

Hi,

I have several hundred servers in the same domain. Each server has the same
scheduled task. I need to change the service acct. password on each server.

After doing some searching and even talking to MS, I haven't found what I'm
looking for. Plus, I suck at scripting.

So..I'm going to use schtasks to write a batch file. However, schtasks only
shows how to do one server at a time. My thought is to write a call in the
script to point to a .txt file which has a list of all the servers I want to
change.

Can someone point me to an example of a script like this or offer up any
suggestions or samples.

I know this issue comes up a lot, yet there doesn't really seem to be
anything concrete. Thanks.

This shouldn't be too hard:
1. Create a one-line batch file containing the appropriate schtask.exe
command. Let's name it xxx.bat.
2. Test it on one or two servers.
3. Place that batch file into a central location that is accessible to
all servers.
4. Create a batch file on your own PC that looks like so:

@echo off
for /F %%a in (c:\Servers.txt) do (
echo Processing server %%a
ping %%a | find /i "bytes=" > nul
if %ErrorLevel% == 0 (
echo %date% %time:~0,5% %%a >> c:\Done.txt
psexec \\%%a \\SomeServer\SomeShare\xxx.bat
) else (
echo %%a >> c:\Missed.txt
)
)

After running this batch file, c:\Done.txt will contain a list
of the servers you were able to reach whereas c:\Missed.txt
will contain a list of those that were unreachable.

A general thought: If you look after several hundred servers
then you could save yourself enormous amounts of time by
using scripting techniques and using tools such as psexec.exe
(which is available from www.sysinternals.com).
