SYMPTOMS
========

When you change the port for the FTP server in the FTP properties of the
Internet Service Manager, the clients still connect on the old port and cannot
connect on the new port

CAUSE
=====

The Services file, used by TCP to assign ports, is not properly updated to
reflect the new port. This file is used to set both the server and client port
settings, and it overrides settings in the registry pertaining to FTP ports.

WORKAROUND
==========

To configure the FTP server for a different port, do the following:

1. Using Internet Service Manager, set the FTP properties to the desired port.

2. Apply the changes and stop the service.

3. Open the Services file (located in the %winnt%\system32\ drivers\etc
  directory.

4. Find the following line and change it to reflect the new port number:

  ftp 21/tcp

5. Save the file, then run the Services.exe file located in the \system32
  directory.

6. Restart the FTP service in Internet Service Manager.
