BIG-IP Edge Endpoint Inspection Failure pre-VPN

 

My government agency uses the F5 BIG-IP Endpoint Inspection. I have a PC that was working fine, that just stopped. I have tried MANY things. Any help to troubleshoot this issue is appreciated.

I have another PC that is working so I have been comparing log files.

(Help desk is a little thin right now, so not much help for this issue)

Error Message:

Reference: NOFWNGFE

I think this is: No Firewall Non-Government Furnished Equipment.

What I have done so far:

- I had McAfee installed, then I deinstalled McAfee, reinstalled, then uninstalled. Now I am just using Windows Firewall and Defender. 

-Reloaded the F5 software and removed any temp files and install locations. Including C:\Windows\Downloaded Program Files\ directory.

-Created a new local admin account, same error when I tried with Chrome and Edge.

  • Spent a day trying many different things. But there were two issues that appear to have resolved this issue:

    • Norton 360 did not fully deinstall and was listed as the Firewall choice.
    • Manually register the DLLs with elevated permissions:
      • Right-click Command Prompt > Run as administrator
        regsvr32 "C:\Windows\Downloaded Program Files\f5OesisInspectorCom4.dll"
        regsvr32 "C:\Windows\Downloaded Program Files\f5OesisInspectorCom.dll"

    I do not fully understand it, but maybe someone here can explain the real fix.
