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. ====================================================================== Keywords : kbinterop Technology : kbiisSearch kbiis200 Version : winnt:2.0 Hardware : ALPHA x86 Issue type : kbprb ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
