Description

Explains limit of two simultaneous VPN sessions per username and errors that result if this limit is exceeded.

Content / Solution:

CloudControl only allows two simultaneous VPN sessions per username. If you need to have more than two VPN sessions at one time then you can create additional Sub-Administrator accounts and use those credentials for the AnyConnect VPN to establish more sessions. For more details, see How to Create a Sub-Administrator using the CloudControl UI.

If you establish a new VPN connection with the same user account when exceeding 2 sessions, one of the other VPN connections will terminate with the following error message:

Windows

The secure gateway has terminated the VPN connection. Close all sensitive networked applications. The following message was received from the secure gateway: Port Preempted

Mac/OSX

The remote peer has terminated the VPN connection. Close all sensitive networked applications. The following message was received from the remote VPN device: Port Preempted

I was trying to log into work but had trouble making a VPN connection. I use Cisco AnyConnect VPN Client. This post describes how to fix the following error messages when using Windows 8 Pro:

  • AnyConnect was not able to establish a connection to the specified secure gateway. Please try connecting again.
  • The VPN client driver encountered an error. Please restart your computer or device, then try again.

The steps to fix this problem are as follows:

1. Edit a registry entry by running a program called regedit. Right-click on it and Run as administrator. Note that I use Start8, by Stardock, to have a Start button and menu. After you left-click on Run as administrator, your computer might ask you to enter the admin password.

2. Go to the appropriate VPN registry directory called ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesvpnva

3. Double left-click the DisplayName key.

An Edit String pop-up window will appear.

The text under the Value data: field on my computer looked like this.

4. Change the field to

by removing all the text and characters that are on the left of the word Cisco.

The end result should look like this:

5. Left-click the ‘OK’ button.

6. Exit the Registry Editor

7. Run Cisco AnyConnect VPN Client and reconnect.

That’s all there is to it. Good luck!

I recently updated my computer on February 13, 2014 with Microsoft’s updates and saw that the text under the Value data: field on my computer looked like this:

@oem10.inf,%VPNVA64_Desc%;Cisco AnyConnect Secure Mobility Client Virtual Miniport Adapter for Windows x64

It is different from what I had originally posted. I’m not really sure how or why it changed and I don’t have time to find out. I also updated to Cisco AnyConnect Secury Mobility Client Version 3.1.04066. As far as I can tell, the value of …

@oem10.inf,%VPNVA64_Desc%;Cisco AnyConnect Secure Mobility Client Virtual Miniport Adapter for Windows x64

.. works, but the value of

Cisco AnyConnect VPN Virtual Miniport Adapter for Windows x64

does not work with Cisco AnyConnect Secury Mobility Client Version 3.1.04066.

Update : 2/15/2014

Changing the Value data: field to

without

@oem10.inf,%VPNVA64_Desc%;

seems to work better, too.
