When using the group policy modeling wizard from either a Windows 7 workstation or Server 2008 DC, I receive the following message in both the summery and settings tab: &nbsp;<br />
<br />
<b>An error occurred while generating report:<br />
The given key was not present in the dictionary</b><br />

This only happens when a user or user container is selected in the wizard. &nbsp;If only the computer selection (OU or specific computer) is selected during modeling the report is generated correctly.<br />

Thanks in advance for your assistance.<br />
