You may need to remove a RAS port from service due to a problem such as physical port or modem failure. Disabling the port prevents RAS clients from dialing in to a bad port and suffering disconnections or lockups. However, you may not have physical access to the server to be able to do this interactively. To disable a RAS port remotely:


 * 1) From a remote computer, log into the RAS server with administrative privilege.
 * 2) Connect to the C$ share on the RAS server.
 * 3) Go into the %System Root%\SYSTEM32\RAS directory.
 * 4) Backup the SERIAL.INI file as SERIAL.OLD. Edit the SERIAL.INI file as follows:
 * 5) Locate the entry in the SERIAL.INI file that references the port to be disabled. For example: [COM1] or [COM2] and remove the entire section.
 * 6) From Server Manager, stop and restart the RAS service.
