IIS 6.0 is not playing well with others...

After looking through various posts and the net, I haven't been able to come to a conclusion in how IIS takes IP's addresses. I know that when you set up a site, you can choose an 'IP' and TCP port for the site in which you can have multiple sites if you have multiple IP's on the box (or set up host header)

My dilemma however, is getting Apace and IIS to run together as I have two seperate applications that require a web server and both need port 80. I've made the necessary changes in the Apache config files (as approved by the Apache board) but IIS continues to eat up both IP's I have on the box (based on a port scan) when I only have one site in IIS binded to a single IP.

Is there some other way to force IIS to use only one IP/port?

You can only have one webserver using port 80, regardless of the IP. If you set up different websites using different IP's, not host headers, you may be able to assign a different port to each website. But regardless port 80 will only go to one application.

Look in the IIS manager for possible settings.

Just wanted to post a resolution - you can have multiple apps running off port 80 -

Went through MSFT KB:

http://support.microsoft.com/default.aspx?scid=kb;en-us;890015

By default IIS listens to all the ipaddress and the ports, if you want to restrict it you can configure ListenOnlyList in the Registry key.Go throught the KB article listed by "Digital Fool" .

That article appears to be a cure for when there is no conflict with another application on port 80 or 443.

Unless you have some kind of intelligent port forwarding agent on the server you can't have different applications using the same port. That is different programs, not different web applications, IIS can run all web applications on the same port.
