Enabling Offer Remote Assistance through Script instead of GPEDIT.

Hi Guys, I hope I find you all well and can help.

Guys, we are building our Windows 7 image, and would like to enable the "Offer Remote Assistance" setting in Local Group Policy (gpedit.msc), but not use GPEDIT.msc to do it.

The reason is as follows:

We wish to add a domain group to the list of helpers for remote control.

We wish to do the following tasks in sequence:

1) Join Machine to domain (done through powershell script)
2) Now, enable the Offer Remote Assistance feature on the machine, and add a domain group to the list of helpers.

Now, as you can see from above, we cannot manually enable the offer remote assistance then add the domain group as a help, prior to the scripts running, since the build is not yet a member of the domain (until the join domain script runs), so we dont have access to that domain group.

So,

Is there an alternative way, through script to:

Enable the Offer Remote Assistance feature.
Then add a domain group as a helper.

Any help greatly appreciated.
