DESCRIPTION
First enumerates all GPOs in the current/target domain using Get-DomainGPO with passed arguments, and for each GPO checks if 'Restricted Groups' are set with GptTmpl.inf or group membership is set through Group Policy Preferences groups.xml files. For any GptTmpl.inf files found, the file is parsed with Get-GptTmpl and any 'Group Membership' section data is processed if present. Any found Groups.xml files are parsed with Get-GroupsXML and those memberships are returned as well.
