## SYNTAX

```
Get-DomainGPOLocalGroup [[-Identity] <String[]>] [-ResolveMembersToSIDs] [-Domain <String>]

 [-ResultPageSize <Int32>] [-ServerTimeLimit <Int32>] [-Tombstone] [-Credential <PSCredential>]
```

## 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.
