Warning
Using Registry Editor incorrectly can cause serious, systemwide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.
When possible, change configuration through Control Panel settings. However, as in the procedure that follows, there are settings that can be changed only by using Registry Editor.

\CurrentControlSet
\Control
\ServiceProvider
\ServiceTypes
\W3SVC
The DWORD Editor dialog box appears.
Your HTTP server now monitors the specified port for all HTTP client requests.
Note
This situation affects the default port on the HTTP server only.
