Cisco NAC Agent Version 4.7.2010.0 Script Error

rb00838-gw · ‎03-29-2010

Whenever this client opens up the NAC Agent to logon to our network, he is greeted with a few not so friendly errors that appear to be javascript/internet explorer related. Anyone have any suggestions how to fix this? We have uninstalled and reinstalled the agent multiple times but to no avail. Have also tried resetting IE settings to default and repairing IE. Nothing. Help? The first screengrab is of the script error window. The second is of what the agent looks like after it opens.

Russell,

Did you try unchecking the "Check for server certificate revocation" option from Internet Properties -> Advanced in Internet Exploder?

Thanks very much for the suggestion; we tried that. We had to open a TAC case and got this solution from Cisco, which worked:

This problem might be due to an improperly registered msxml3.dll .

Please try the following procedure to reregister msxml3.dll and then rerun the agent install

1. Uninstall the Cisco Nac Agent from the system.

    2. Just to be sure manually wipe out directory "C:\Program

Files\Cisco\Cisco NAC Agent" in case the uninstall left anything behind.

    3. Download regrserv32a.exe from

http://support.microsoft.com/kb/267279

    4. Run regserva.exe - this will extract regserv32.exe on disk

    5. Open a command prompt and cd to the directory where regserv32.exe

extracted.

    6. Run regsvr32.exe msxml3.dll (it will pop up a dialog saying the

registration was successful.

    7. Then re-install the NACAgent.

    8. Agent should now pop up (script error symptom should now be

eliminated)
