RE: Reboot Script for Group Policy?

Hi John,

You need to pass text file name as command line argument to the script.
For example, if you have saved the script with name "RebootComputers.vbs"
under d:\ , then you need to call this script using following syntax
(assuming name of text file is d:\machineInfo.txt)

cscript d:\RebootComputers.vbs d:\machineInfo.txt

here, "d:\RebootComputers.vbs" is full path to your script,
and, "d:\machineInfo.txt" is full path to text file containing machine name
along with reboot times.

Hope it helps :)

Regards,
Umesh
