Problem: 

The following error occurs when clicking on the "SNMP Profiles" link in the NFA Administration GUI:

Microsoft VBScript runtime error '800a01fa' 
Class not defined: 'SettingsDB' 
/nqsrv_nav.asp, line 111 

 

A browser on a remote client machine may simply show an "HTTP 500 Internal Server Error".

Environment:

NFA 9.3.2

 

Cause:

This has been observed to occur after installing NFA 9.3.2 without first installing the prerequisites listed here

https://wiki.ca.com/pages/viewpage.action?pageId=234758388

The problem persists even after uninstalling NFA, installing the prerequisites, and reinstalling.

 

Resolution:

1. Open the IIS Manager and expand "Default Web Site".

2. Check whether there is a blue "Globe" icon next to "Admin", as shown in the following screenshot:

3. This means that "Admin" is listed as an Application, and the error described in this article will occur.

4. To resolve this, right-click on "Admin" and select "Remove" as shown:

5. Then, run "IISRESET" from a Command Prompt.

6. Log back into NFA and verify that you can now see the Admin page properly.
