Symptoms

Assume that you use Active Directory cmdlets to interrogate Active Directory objects on a computer that is running Windows Server 2008 R2 or on a Windows 7-based computer that has the Remote Server Administration Tools feature installed. When you try to run the Get-ADObject cmdlet, you receive an error message that resembles the following:
The given key was not present in the dictionary.

Cause

This issue occurs because the cmdlet query returns an attribute that is not listed in the aggregate schema. When the Windows PowerShell cmdlet formats the attributes for the result of cmdlet query, the cmdlet retrieves a list of interesting attributes from Active Directory to track the formatting operation. Then, the cmdlet compares this list against the list of attributes that are retrieved for the aggregate schema. When the cmdlet query returns an attribute that is not listed in the aggregate schema, the issue that is described in the "Symptoms" section occurs.
