Install the SonicWall Terminal Services Agent (TSA) on one or more terminal servers on your network within the Windows domain. The SonicWall TSA must have access to your SonicWall network security appliance, and the network security appliance must have access to the TSA. If you have a software firewall running on the terminal server, you might need to open up the UDP port number for incoming messages from the network security appliance.
SonicWall TSA is available for download without charge from MySonicWall.
For instructions on installing the SonicWall TSA, see the SonicWall Directory Services Connector Administration Guide. You can download this guide from https://www.sonicwall.com/support/technical-documentation/.
