try this, snipped from faq from lou rieger:
Q: How can I keep current copies of the Registry settings of all machines in a central location on a server?
A: It is quite a good idea to have the files which are necessary to make an Emergency Repair Disk (ERD) on another machine. You have to copy these files onto a floppy only when you need them. So you are sufficient prepared for a Registry crash when you copy these files on a regular basis to another machine. You can do this without expenses with NT's own tools. All you have to do is going through the following steps:
1. Let the Scheduler service on all machines run under an admin account
2. On SERVER, create a directory ERDs
3. Share this directory as ERD$
4. Give only admins the rights to access both directory and share created in steps 2 and 3
5. Copy the following batch file erd.cmd into a directory where only admins have access on every machine:
@echo off
REM To repair a NT installation, format a floppy and copy all
REM files from the \\SERVER\erd$\%computername%\ onto
REM the floppy to get the ERD you need.
echo.
echo Backing up ERD info to \\SERVER\erd$\%computername%
echo.
if exist "\\SERVER\erd$\%computername%" goto ok
md "\\SERVER\erd$\%computername%"
:ok
rdisk /s-
copy %SystemRoot%\repair\* "\\SERVER\erd$\%computername%\"
echo Backup complete.
echo.
6. Schedule a periodical job for erd.cmd on every machine
Now in case a you have to repair a NT installation on one of your machines, you have to format a floppy on the server and copy all files from the \\SERVER\erd$\%COMPUTERNAME%\ directory onto the floppy to get the ERD you need.
Credits go to Lou Rieger, who amended the script so that it does work now also for machines with spaces in their names.
