When you listen to a radio station and the announcer says, You are listening to 91.5 FM WRKX The Rock!, what the announcer means is that you are listening to a radio station broadcasting an FM radio signal at a frequency of 91.5 megahertz, with FCC-assigned call letters of WRKX.his band of the radio spectrum is used for no other purpose but FM radio broadcasts. In the same way, AM radio is confined to a band from 535 kilohertz to 1,700 kilohertz (kilo meaning thousands, so 535,000 to 1,700,000 cycles per second).
For either Windows XP or Vista, TCP port 3389 (which Remote Desktop uses) must be forwarded to the Remote Desktop PC. If you are setting up Web access, you also must forward TCP port 80 (or the non-default port you set) to the host computer.
One of the most common remote desktop issues is a failure of the underlying network. To check for connectivity, try plugging a laptop into the network port from which the user is trying to connect, and then use the Ping or Tracert command to see if it's connected to the host server or connection broker.
