Unable to use Windows Remote Assistance on multiple XP SP3 computers

95 % of the computers in our estate are Win XP SP3 machines

We are trying to resolve the windows remote assistance issue on several computers by running the following start up script

We have deployed the following .bat file (which is saved in the netlogon share) as the first step

Echo Fixing Problem Registry Key

REM Set the File Name [user temp directory]EnableRA.reg and delete if already present

SET tempreg=c:\sms\EnableRA.reg

REM Write the Reg File

I also run the sessmgr.exe -service as the second step in the GPO

however this doesn't seem to resolve the issue even after a computer is rebooted.

When i run the following process manually it works every single time

1. Manage the computer - go into System tools - local users and groups - users - helpassistant - untick 'account is disabled'

2. run psexec \\remotecomputer -s sessmgr.exe -service

3. reboot the computer

I cant keep doing the above for every pc in the estate and hence I am desperately looking for script that will do the above 3 steps (can do without the reboot though) that can potentially be deployed using GPO - startup scripts.
