How to Remotely Disable a RAS Port

ID: Q147717

The information in this article applies to:
  • Microsoft Windows NT Server versions 3.5, 3.51, 4.0
  • Microsoft Windows NT Workstation version 4.0
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.
