Bug in Get-AdGroupMember

Is there an official bug in Get-AdGroupMember?

If you use this commandlet on a group which contains members from a diffrent domain it throws an error.

Is this a bug? and if so will MS fix it?

I think you be be interested in this thread that i found by google searching your problem.
It discusses the problem at length and has a work around.


I just ran Get-ADGroupMember on a group in my child domain that contains computers from both the child and parent domain with no errors. Maybe it is an issue with an older version of PowerShell? I am running 5.0 RTM

Thanks for the reply,

My main problem is with the commandled not working. I already have my own work around, but the correct way would be to use the commandled. I just want to know if MS is aware of the bug and if they are going to fix it.

This is my work around:

   $members= (Get-ADGroup -Identity $groupSID -Properties members).members
   if ($members) {
        foreach ($member in $members)
            if ($member.contains("ForeignSecurityPrincipals")) {
                    $pos = $member.IndexOf(",")
                    [string] $memberSID = $member.substring(3,$pos - 3)
