I am trying to force web clients too use SSL when accessing my email server.  If I leave the default port too 443, then I get errors indicating that something else is using 443.  The machine is win 2k server running Symantec AV, IIS, Active Directory.  What is using this port, IIS.  Can I tell IE webbrowser too use different port for SSL?

To force users to use SSL on an IIS server, right-click the Default Web Site, click Properties, Directory Security tab, click "Edit" on the Secure Communications section, and check the box marked "Require secure channel (SSL)".

If your web server is unable to bind to port 443, that's a different problem.  What are you doing specifically that gives you the error that port 443 is already in use?  

Download ActivePorts from to see which application has that port in use.

visioneer - I went too the website but I don't see any programs called "activeports"?  However a utility that does this will definately help me solve this problem.  Is it true that XP and server 2003 have internal utilities that tell what port an application is using?

It's under their "freeware" section.

The following command will show what ports are in use, but it's not as easy to read as ActivePorts:

netstat -an

visioneer - Ok I found it, below is a user review on cnet of this software.  Is this guy correct?

"If you really care you will read this for your sake in your computers TO"
Warning do not install this software it has a Trojan built into it and will allow the hacker direct access to your computer take it from me I know. the virus File names: Aports.exeThis threat is a stand-alone application, does not drop files, and does not modify the registry. This hack tool displays a Graphical User Interface (GUI) showing the processes and applications as they are mapped to port numbers. Also, it shows the IP address of the user accessing open ports.The publisher also offers an API for a fee. Aports.exe is freeware in its GUI form

I've never heard of this program having a Trojan, and I've scanned it with multiple apps.  This is news to me.

The problem was IIS was already using 443 and I was telling my email servers webserver to use 443.  I have told it to use something else and it works.  Thanks for the utility.  Do you know of any others that are completely free and have any other functionality.
