Make IIS6 not listen on one IP

Question

I have another service that needs to use multiple ports on one IP of a server. When IIS starts, it uses all unused IPs so the other service fails to bind its IP. If I start the other service first it is able to use the IP but I can't rely on the order of services starting or that they won't need to be restarted at some point. Is there any way to make IIS not use an IP at all?

Answer 1

Apparently in IIS6 the UI setting is broken and this needs to be done using httpcfg of which the gist is:

Type the following, where xxx.xxx.x.x is the IP address you want to add:

httpcfg set iplisten -i xxx.xxx.x.x

When this succeeds, Httpcfg returns the following: HttpSetServiceConfiguration completed with 0

To view additional status codes, see the Httpcfg help. After the IP address is added, use the following command to list it:

httpcfg query iplisten

Httpcfg returns the following: IP :xxx.xxx.x.x. Restart the service

I finally found the answer:

There's a utility called httpcfg.exe that can be used to specify on which IPs IIS will listen.

Sure. Fire up Internet Information Services Manager. Expand until you see your sites under "Web Sites."

For each site, right-click and choose Properties. On the Web Site tab click "Advanced" next to IP Address and fill in only the addresses you want used (instead of the default "All Unassigned")
