Issue:
Error below is seen when creating a new custom report, site to site report, or analysis report.
 
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

When loading the browser locally on the NFA server it reveals a more detailed error:

Server object error 'ASP 0177 : 8000ffff'

Server.CreateObjectFailed

D:\NETQOS\REPORTER\WEB\COMMON\../common/LegacyInterop.asp line 22

8000ffff




Or:
ActiveX component can't create object
 
Environment:
NFA and ReporterAnalyzer all versions.
Cause:
Microsoft pushed Windows Updates that lock down ASP.NET in IIS. 
Resolution:
1. Windows Server 2008: Right click on Computer, click Manage, expand Configuration, expand Local Users and Groups.
    Windows Server 2012: Hit the start button and search for "Edit Local Users and Groups".

6. Then right click on the \CA\NFA or \Netqos\ directory and select properties.

7. Select the Security tab, and add the IUSR account and give it full permissions.

8. Do the same exact thing for the IIS_IUSRS account with full permissions.
