How to Exceed the Maximum Number of Allowed Objects from Get-ADGroupMember, Get-ADPrincipalGroupMembership, and Get-ADAccountAuthorizationGroup cmdlets

By
One of the reason why the cmdlets in the ActiveDirectory module limit the properties from objects or the number of objects returned is because you may accidentaly ask for 2 billion objects if you are not careful.  A recent question from one of my posts asked about how to exceed the threshold for Get-ADGroupMember. 
The error that the user received was:
Get-ADGroupMember : The size limit for this request was exceeded
The default limit is 5000 objects.  This is a limitation imposed by the Active Directory Web Service.  ADWS is a requirement for utilizing the ActiveDirectoy module for PowerShell. If you have multiple instances on ADWS on multiple Domain Controllers, you will need to perform this procedure on each one.  Since you do not know for sure which DC your client will bind to, changing this setting on all of the ADWS services will prevent random issues from happening in the future.
On the file c:\Windows\ADWS\Microsoft.ActiveDirectory.WebServices.exe.config
After the <appSettings> tag, place this entry:
<add key=”MaxGroupOrMemberEntries” value=”10000”/>
This assumes that you need to return up to 10000 objects from these cmdlets.  Also take note that you will still have a 5 minute timeout imposed on all your requests.  If you cannot recover the information in 5 minutes, the request will fail.  Filter your request to contain only the information that you need to work with.
Your next steep is to stop and then restart the ADWS service on the Domain Controller.

How to run GPResult on a remote client with PowerShell

By
In the past, to run the GPResult command, you would need to either physically visit this client, have the user do it, or use and RDP connection.  In all cases, this will disrupt the user.  First, you need PowerShell remoting enabled on the target machine.  You can do this via Group Policy .

Error icon when creating a GPO Preference drive map

By
You may not have an error at all.  Take a look at the drive mapping below. The red triangle is what threw us off.  It is not an error.  It is simply a color representation of the Replace option of the Action field in the properties of the drive mappings. Create action This give you a green triangle. The Create action creates a new mapped drive for users. Replace Action The Replace action gives you a red triangle.  This action will delete and recreate mapped drives for users. The net result of the Replace action is to overwrite all existing settings associated with the mapped drive. If the drive mapping does not exist, then the Replace action creates a new drive mapping. Update Action The Update action will have a yellow triangle. Update will modify settings of an existing mapped drive for users. This action differs from Replace in that it only updates settings defined within the preference item. All other settings remain as configured on the ma...
