Sorry, I don't have access to pastebin at work (blocked) but I need some help with a module. This is the closest that I have found to do what I need, but it is way more complicated than I have skill in powershell.
https://learn-powershell.net/2013/08/11/get-all-members-of-a-local-group-using-powershell/
The problem I am having is the module is not enumerating groups out side of the domain the servers it is being run against exist on.
For example:
Servera.sitea.com has two security groups, both with nested security groups and members.
When run I will get:
siteA/Group1
--siteA/Member1
--siteB/Member2
----siteA/Group2
------SiteA/Member3
------SiteA/Member4
SiteB/Group1
.
.
.
.
Nothing will be populated under the second domain's group. I do have access, if i run a get-adgroupmember against the SiteB/Group1 it does return members.
The problem I believe is in the script. There is a section where it strips the full name from the groups. What I am thinking is that it strips the domain suffix before doing the lookup. Then when it does a lookup of that security group on
the default domain (SiteA) it can't resolve the (SiteB) group.
That, or it is something similar to when you do a "Get-ADGroupMember" lookup. If you are searching for an account on another domain you have to specify the -server switch and specify the other domain controller. Would this need to be
passed through some how for groups not found on the same domain? Can it be specified manually?
Is there any way to correct this? I am trying to run an audit on a hundred or so servers for who has administrator access. I need to know who is in the base group, and who is inheriting admin access through sub/nested groups (while showing in
the output which group they belong to).
Here is the section **I THINK** that the problem is stemming from.
