What To Do

You must make changes to the registry keys listed below. Sophos recommends that you make a backup copy of the registry, before making any changes to it.

  1. Change
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Sophos Message Router | ImagePath
    "C:\Program Files\Sophos\Remote Management System\RouterNT.exe" -service -name Router -ORBListenEndpoints iiop://:8193/ssl_port=8194
    "C:\Program Files\Sophos\Remote Management System\RouterNT.exe" -service -name Router -ORBListenEndpoints iiop://:8193/ssl_port=8198
  2. Change
    HKEY_LOCAL_MACHINE\SOFTWARE\Sophos\Messaging System\Router | ServiceArgs
    -ORBListenEndpoints iiop://:8193/ssl_port=8194
    -ORBListenEndpoints iiop://:8193/ssl_port=8198
  3. Restart the
    • Sophos Message Router service
    • Sophos Agent service


  1. If you 'reprotect' the computer, setup.exe will obtain the values from the mrinit.conf file in the CID, and the port numbers will revert back to the default.
  2. For 64-bit computers:
    • ServiceArgs is located at: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Sophos\Messaging System\Router
    • RouterNT.exe process is located at: C:\Program Files (x86)\Sophos\Remote Management System\RouterNT.exe
