To aid in troubleshooting Windows DirectAccess client configuration and connectivity, Microsoft recently made available the Windows DirectAccess Client Troubleshooting Tool. The tool, which is a portable executable based on the .NET Framework and does not require installation, operates by performing a series of tests and health checks on a connected DirectAccess client. As of this release, the troubleshooting tool checks network interface configuration, Network Location Server (NLS) reachability, IP connectivity and the status of transition technologies, Windows Firewall with Advanced Security configuration, computer certificate status, as well as network connectivity over the infrastructure and user IPsec DirectAccess tunnels.
The tool also features an optional debug mode that provides highly detailed information gathered from each of the tests executed.
The tool is supported on both Windows 7 and Windows 8.x clients. If you implement or support DirectAccess, this utility will certainly speed up your troubleshooting by providing deep insight in to the configuration and current connectivity status for your DirectAccess clients.
