Troubleshoot

This section provides information you can use in order to troubleshoot your configuration.

Using DART to Gather Troubleshooting Information:

DART is the AnyConnect Diagnostics and Reporting Tool that you can use to collect data useful for troubleshooting AnyConnect installation and connection problems. DART supports Windows 7, Windows Vista, Windows XP, Mac version 10.5 and 10.6, and Linux Redhat. The DART wizard runs on the computer that runs AnyConnect. It assembles the logs, status, and diagnostic information for Cisco Technical Assistance Center (TAC) analysis and does not require administrator privileges.
Although DART does not rely on any component of the AnyConnect software to run, yet you can launch it from AnyConnect, it will collect the AnyConnect log file, if it is available. Currently, DART is available as a standalone installation, or the administrator can push this application to the client PC as part of the AnyConnect dynamic download infrastructure. Once installed, the end user can start the wizard from the Cisco folder available through the Start button.
