Hi, @kilo1548, I have to image a bunch of devices for one of our clients. you really just need to modify the service definition to use a new GUID for the "s=" parameter. As luck would have it, I wrote a script specifically to address this problem. I've made it as generic as possible specifically so other people could benefit from it. It also has the ability to assign a specific GUID to a device should you need that capability (I did). With the GUID-assignment feature you could set the first 2 groups to represent a specific client or dept, for example. Or you could use it to re-create your image from one of your clones so that it is as consistent as possible. Or to emulate another device to test out commands or whatever. I've found several effective use-cases for it. It works very well, though you must REBOOT (not simply RESTART the service) if you are using it from within the Commands feature, since restarting the service there kills the process that's trying to restart the service, resulting in the service not coming back up. Save it as newscid.vbs and call it like so: Code:cscript.exe //nologo newscid.vbs reboot new
or Code:cscript.exe //nologo newscid.vbs reboot 12345678-1234-1234-1234-1234567890ab
You can even use an extension to run this from the Commands for a specific device GUID so that it will automatically run every single time one of the vanilla clones comes online (add whatever other customizations you need to it as well and you've got an easy way to prep 'em all). :) Code:'//=============================================================================
