WebVPN dosen't work after a Windows 7 update.

rexpetersen · ‎05-10-2012

Hi

Today a costumer called me with a strange problem

After a Widows 7 update two days ago all their WebVPN users could not log on.

The web browser comes with a popup with the message: This web location wants to install the following add-on: "Cisco Portforwarder Control by Cisco"

But nothing happens ?

If they remove the Windows 7 update, WebVPN works again.

Anyone there know what the problem could be and what to do to make it work ?

Best regards

Hi Rex

Do you mind telling us which update was the problem? Then I do not need to uninstall them all :-(

I just asked a similiar question, after Windows XP update RDP bookmarks don't work. It worked for me after uninstalling Internet Explorer KB2675157 update, is the same one?

I had RDP through my SSL VPN working great. I then tried to figure out port forwarding and smart tunnels but couldn't get it to work, so I turned it off.

Now every time I connect to my SSL page and click on a RDP link in the portal, I get the pop-up stating it wants to install the add-on for cisco portforwarder, doesn't matter what I try it will never launch the RDP...not sure how I'm going to fix this one. There is a reason Juniper smokes Cisco when it comes to SSL VPNs!

Hi All,

If I am not wrong, the only application that has been affected because of the Microsoft update is clientless vpn. It is because of the Microsoft Security update KB 2695962. For more information please visit:

The resolution to this can be found at:

http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120314-asaclient.

Though this link provide a workaround but I have not seen that working.

There are two options to make it to work:

1. Either uninstall the specified security update

or

2. Upgrade the code to the code mentioned under Software Versions and Fixes of the link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120314-asaclient

Let me know if this works after performing these steps.

Thanks,

Vishnu Sharma

I am going to upgrade to the latest ASA code....but this was working yesterday and only stopped when I started trying to get smart tunneling and port forwarding working. I have turned it all off and deleted that configuration and I still get the pop up to install the cisco port forwarder...but it's already installed. Odd and stupid problem.
