Hi,
Here's what we did...
Create a folder somewhere, ours is on VOL1 and give the users rights (RWCM) and put a space restriction on it.
In there, we put regedit (in case it's not on the PCs) and a batch file. The batch file goes like:
START /w REGEDIT /e %temp%.\tmp.txt HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ComputerName\ComputerName
MAP ROOT H:=SERVERNAME\VOL1:\LOGS
TYPE %temp%\TMP.TXT >>h:\COMP-NAME.TXT
EXIT
This pipes out the key specified to tmp.txt, then this is written up to the server, appended to a file called COMP-NAME.TXT
Hope this helps . . .
