Use this information if the PerformanceGuard agent on a computer won't connect to the PerformanceGuard system even though the computer is otherwise online.
You can only do this if you're a PerformanceGuard administrator.
When that's the case, the computer never appears when you search for it in the PerformanceGuard web interface (ANALYZE > Computers > Computer Search). Alternatively, it does appear, but with a yellow or red status.

How It Should Work

When everything works correctly, the agent should connect to the PerformanceGuard Frontend server. The Frontend server in turn sends the agent's data to the PerformanceGuard Backend server, which in turn lets you view the data in the PerformanceGuard web interface, in reports, and through e-mail notifications.

Possible Cause

The most likely reason why the agent isn't able to connect is that the agent isn't configured to use the correct IP address and port number of the PerformanceGuard Frontend server.
Another reason may be that a network problem or firewall prevents the computer that has the agent installed from connecting to the Frontend server.
In the following we will check that the agent has the correct information about the Frontend server. If required, we will also check the connection between the computer that has the agent installed and the Frontend and Backend servers.
