Keep in mind the following: All AnyConnect modules and profiles can be predeployed. The solution to is to: Run a bit version of Internet Explorer. Because of the use of SHA-2 timestamping certificate service, the most up-to-date trusted root certificates are required to properly validate the timestamp certificate chain. You will not have this issue with predeploy or an out-of-the-box Windows system configured to automatically update root certificates.
You can also use the signtool to verify if the issue is outside of AnyConnect by running the signtool.

Note If some applications such as Microsoft Outlook do not operate with the tunnel, ping a known device in the network with a scaling set of pings to see what size gets accepted for example, ping - , ping - , ping - , and ping - Determine What Conflicted With Service Determine What Conflicted With Service The following procedure determines if the conflict is with the initialization of the server at boot-up or with another running service, for example, because the service failed to start.
Solution Uninstall Kaspersky and refer to their forums for additional updates. Problem If you are using RRAS, the following termination error is returned to the event log when AnyConnect attempts to establish a connection to the host device:. Problem The connection fails due to lack of credentials. Solution The third-party load balancer has no insight into the load on the ASA devices. Because the load balance functionality in the ASA is intelligent enough to evenly distribute the VPN load across the devices, we recommend using the internal ASA load balancing instead.
Problem The AnyConnect client fails to download and produces the following error message:. Solution Upload the patch update to version 1. A new version of mDNSResponder 1. To resolve this issue, a new version of Bonjour is bundled with iTunes and made available as a separate download from the Apple web site.

Problem If you are using a EVDO wireless card and Venturi driver while a client disconnect occurred, the event log reports the following:. Check the Application, System, and AnyConnect event logs for a relating disconnect event and determine if a NIC card reset was applied at the same time. Ensure that the Venturi driver is up to date.
Disable Use Rules Engine in the 6. Solution Connect to a Linksys router with factory settings. This setting allows a stable DTLS session and no interruption in pings.
Add a rule to allow DTLS return traffic. If third-party software is intercepting or otherwise blocking the operating system API calls while retrieving network interface information, check for any suspect AV, FW, AS, and such.

To provide AnyConnect users with help, create a help file with instructions about your site and load it on the Adaptive Security Appliance. When users connect with AnyConnect, AnyConnect downloads the help file, and displays the help icon on the AnyConnect user interface.
When the user clicks the help icon, the browser opens the help file. The help file will be downloaded to the client PC. Click the help icon to open the help file in the browser. If the help icon does not appear, check the help directory to see if the AnyConnect downloader was able to retrieve the help file.
AnyConnect lets you download and run scripts when the following events occur:. Upon the establishment of a new client VPN session with the security appliance.
We refer to a script triggered by this event as an OnConnect script because it requires this filename prefix. Upon the tear-down of a client VPN session with the security appliance. We refer to a script triggered by this event as an OnDisconnect script because it requires this filename prefix.
The establishment of a new client VPN session initiated by Trusted Network Detection triggers the OnConnect script assuming the requirements are satisfied to run the script , but the reconnection of a persistent VPN session after a network disruption does not trigger the OnConnect script.
Some examples that show how you might want to use this feature include:. Refreshing the group policy upon VPN connection. Mapping a network drive upon VPN connection, and un-mapping it after disconnection. Logging on to a service upon VPN connection, and logging off after disconnection. AnyConnect supports script launching during WebLaunch and stand-alone launches.
These instructions assume you know how to write scripts and run them from the command line of the targeted endpoint to test them. The AnyConnect software download site provides some example scripts; if you examine them, remember that they are only examples.
They may not satisfy the local computer requirements for running them and are unlikely to be usable without customizing them for your network and user needs. Cisco does not support example scripts or customer-written scripts.
Be aware of the following requirements and limitations for scripts:. It looks for a file whose name begins with OnConnect or OnDisconnect regardless of file extension. The first script encountered with the matching prefix is executed. Script Language—The client does not require the script to be written in a specific language but does require an application that can run the script to be installed on the client computer.
Thus, for the client to launch the script, the script must be capable of running from the command line. AnyConnect hides the cmd window during the execution of a script on Windows, so executing a script to display a message in a. Enabling the Script—By default, the client does not launch scripts. Use the AnyConnect profile EnableScripting parameter to enable scripts.
The client does not require the presence of scripts if you do so. When running on a bit Windows version, it uses the bit version of cmd. Because the bit cmd. For example, the msg command, supported by the bit cmd. Therefore, when you create a script, use commands supported by the bit cmd. Write and test your scripts on the targeted operating system.
If a script cannot run properly from the command line on the native operating system, then AnyConnect cannot run it properly. If you use ASDM version 6. For example, if you import the script myscript. If you use an ASDM version earlier than 6. To ensure the scripts run reliably, configure all ASAs to deploy the same scripts. If you modify or replace a script, use the same name as the previous version and assign the replacement script to all of the ASAs that the users might connect to.
When the user connects, the new script overwrites the one with the same name. Use an enterprise software deployment system to deploy scripts manually to the VPN endpoints. If you use this method, use the script filename prefixes below:. Install the scripts in the following directory:. On Linux, assign execute permissions to the file for User, Group and Other. Check Enable Scripting. The client launches scripts on connecting or disconnecting the VPN connection. Check Terminate Script On Next Event to enable the client to terminate a running script process if a transition to another scriptable event occurs.
On Microsoft Windows, the client also terminates any scripts that the On Connect or OnDisconnect script launched, and all their script descendents.
If a script fails to run, try resolving the problem as follows:. Make sure that the script has an OnConnect or OnDisconnect prefix name.
Write, Test and Deploy Scripts shows the required scripts directory for each operating system. Try running the script from the command line. The client cannot run the script if it cannot run from the command line. If the script fails to run on the command line, make sure the application that runs the script is installed, and try rewriting the script on that operating system.
If the client downloads an OnConnect script from an ASA, then downloads a second OnConnect script with a different filename suffix for another ASA, then the client might not run the script you intended to run. If the script path contains more than one OnConnect or OnDisconnect script, and you are using the ASA to deploy scripts, then remove the contents of the scripts directory and re-establish a VPN session.

However, if you deploy your own executable to customize the GUI, the executable can call resource files using any filename. You can customize AnyConnect by importing your own custom files to the security appliance, which deploys the new files with the client. The file now appears in the list of objects.

Logo icon that appears on the main screen in the top-right corner. To provide AnyConnect users with help, create a help file with instructions about your site and load it on the Adaptive Security Appliance.
When users connect with AnyConnect, AnyConnect downloads the help file, and displays the help icon on the AnyConnect user interface. When the user clicks the help icon, the browser opens the help file. The help file will be downloaded to the client PC. Click the help icon to open the help file in the browser.
