How to search a different Active Directory Domain with Powershell Get-ADGroupMember

Question: I'm using the Powershell Get-ADGroupMember  to  iterate through various  Groups and return the members. This is working OK - as long as I'm searching  in AD groups which are on the same domain server as the server I'm currently logged on.

For example - I've logged onto the domain : mydomain1.admin.net . I have authority to check AD groups in this domain. But if I then attempt to do a search on another domain e.g mydomain2.admin.net , even though the domain is in the same AD farm , the Get-ADGroupMember will not find the group.

To make things more confusing - if there is a  mydomain2 AD group nested in a mydomain1 AD groups and I use Get-ADGroupMember than the Powershell cmdlet will return all the members , including the nested group. 

Yet , If I attempt to search only the mydomain2 group - NO GO!

Is there a way to search directly on another domain using Get-ADGroupMember?

Answer: The behaviour you've outlined is the way it works. Now, if you want to access the other domain directly but within the same Active Directory , than this can be completed by using Get-ADGroupMember and the -server switch. 

This is an example of how you would use the -server switch . This assumes your current logon is resolved on mydomain1.admin.net but then you need to check the AD group on mydomain2.admin.net 

Get-ADGroupMember -server 'mydomain2.admin.net'  -identity 'DBASupport' -Recursive

Once you access the data there are all sorts of usages - commonly I use  the Powershell Get-ADGroupMember  method to get base data for SQL Server security audits , it audit, certification ,
