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.
