Palo Alto Terminal Server Agent Upgrade
Palo Alto Networks makes a program named Terminal Server Agent, aka the TS Agent. It is similar to the User-ID agent. However, the TS Agent is built to identify users on a multi-user system.
In this post, I will show you step-by-step how to upgrade the Palo Alto Networks Terminal Server agent.
Prerequisites
- Verify that the new Terminal Server agent version is compatible with your PAN-OS.
The TS Agent is typically compatible with the same release number along with earlier still-supported PAN-OS versions. For example, TS agent 11.0 works with PAN-OS 11.0 and earlier. You can confirm this by reading the OS Compatibility section in the release notes.
The Process
- Log in to the Palo Alto Networks Customer Support Portal.
- Click on Updates.
- Click on Software Updates.
- Select the Terminal Services Agent.
- Click on the version you need to start the download.
- Connect to the system that is running the Palo Alto TS Agent.
- Open Services.
- Stop the PAN Terminal Server Agent service.
Most of the settings for the TS agent appear to be saved in the registry.
- Export the registry key
HKLM:\SOFTWARE\Palo Alto Networks\TS Agent
to backup your settings.
There are some settings such as certificates stored in the installation folder.
Typically the TS agent is installed to C:\Program Files\Palo Alto Networks\Terminal Server Agent
- Backup the Terminal Server Agent installation folder.
- Start installing the new version of the TS Agent.
- Click Next.
- Select the install folder to which the Terminal Server agent is installed and click Next.
- Start the installation by clicking Next.
- Wait while the new Palo Alto Terminal Server agent is installed over the existing Terminal Server agent.
- Click Close to exit the installer.
- Confirm that the PAN Terminal Server Agent service is running.
- Open the Terminal Server Agent program.
- Confirm that everything is connected and all your configurations from the old version are present.
If you run a Palo Alto firewall in HA in the Active/Passive configuration, only the active firewall will show as connected.
- Log in to the Palo Alto Networks firewall.
- Click on Device.
- Click on User Identification.
- Click on Terminal Server Agents.
- Confirm that the Terminal Server agents are connected.
That’s all it takes to upgrade the Palo Alto Terminal Server Agent.
