I can no longer use Get-ADPrincipalGroupMembership on Windows 8.1 enterprise. Whenever I run the cmdlet I get this error:

Get-ADPrincipalGroupMembership : The server was unable to process the request due to an internal error.  For more information about the error, either turn
on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send
the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework SDK documentation and inspect the server trace logs.

    + FullyQualifiedErrorId : ActiveDirectoryServer:0,Microsoft.ActiveDirectory.Management.Commands.GetADPrincipalGroupMembership

This happens whether I pipe an AD user to the cmdlet or use explicit parameters. I found one other article where this happened because some group names contained a "/" character, but I have verified that none of our groups contain anything other than alphanumeric characters, spaces, and ampersands.

I have tried fully removing and re-installing the Windows 8.1 RSAT, but this did not fix the issue. To work around this I am currently running AD cmdlets on a server, but would like to fix this on my workstation.

I am running PS version 5.0.10105.0. I know this is a preview version, but I have been running the previews since the February release and this has been working until now. Thanks!

Does anyone know why this might be happening?

Richard,

Thanks for the detailed response!

I really don't think the "/" is the issue as this works on at least one other computer (Server 2012 R2 with PS 4.0) but stopped working on my workstation with 8.1 and PS 5.0. I ran the command below and got no results:

get-adgroup -Filter * | where distinguishedname -like '*/*'

Isn't $_.distinguishedName required after the pipe? I use:

Get-ADGroup -Filter * | Where {$_.distinguishedName -Like '*/*'}

Isn't $_.distinguishedName required after the pipe? I use:

Get-ADGroup -Filter * | Where {$_.distinguishedName -Like '*/*'}

In any case, there appears to be a new problem with the PowerShell V5 Get-ADPrincipalGroupMemebership. I don't have PS 5 so I cannot tes
