Thanks @robert.mueller

I took the code and tweaked it a bit via ChatGPT, pasted it back here (pasting it lost some of the powershell syntax such as some "#" but I hope it is ok!)

This script expects that your agents have the custom fields "LAPS Username' and 'LAPS Password'

I had a nightmare getting powershell to recognise that the user existed and could be added to the group so dumbed it down to use "net groups" command instead

Also this Atera code box formatting is whack !

Apologies @robert.mueller I don't often visit these pages so have only recently seen your reply.

The script is working for me here still creating/updating passwords and also updating the Atera console with the new detail.

If you are still having problems we can liaise directly to see if any information I can provide helps to resolve it.

Thanks Laurie,

Where about would you put this extra bit ?
