Hi,
I have windows 2003 server and two IP addreses, on one IP I run OMNIHTTP web server and on another IP I want to run IIS web server. Unfortunatelly IIS does not start, it says that service is in use. I think it is something wrong with Port, as I understand OMNIHTTP use 80 port and IIS can't bind to it.
Any suggestion how to solve this problem? I know that it is possbile to run two web servers on the same machine but don't know exactly how to do that.

Change the port that one of the HTTP services use.

I want to host web page and point domain to web server. So if I change port, it will not work. Right?

You need to bind the IIS web page to only one IP address (in the properties of the page), and tell Omnihttp to bind only to the other IP address (however that works with this software). So the problem is not with the port, it's that currently Omnihttp is listening on all addresses.

I have done so. I have entered one IP address in OmniHTTP and second in IIS.

>>So the problem is not with the port, it's that currently Omnihttp is listening on all addresses.

If I change IIS port from 80 to 81, IIS starts without problem. Does it means that problem not in IP but in Ports?

Open a command prompt and enter
netstat -a -n -b
to find out which process is using port 80 currently.
Or download Sysinternal's TCPView (http://www.sysinternals.com/Utilities/TcpView.html) to do the same with a graphical interface.

I have got result below. 65.23.156.MyFirst - is my first IP address, I have removed last digit for security reason.

......
 TCP    0.0.0.0:80             0.0.0.0:0              LISTENING       2692
 [OHTTPD.exe]

  TCP    65.23.156.MyFirst:80         4.255.236.124:1583     ESTABLISHED     2692
  [OHTTPD.exe]

  TCP    65.23.156.MyFirst:80         59.167.233.195:50258   ESTABLISHED     2692
  [OHTTPD.exe]

That means that Omnihttp is listening on all IP addresses in the system; you need to disabled this and tell it to only listen on the assigned address, in order to free the port on the other IP address for IIS.

Maybe do you know why OmniHTTP act so? I have entered IP address in OMNIHttp to listen only on 65.23.156.MyFirst.

It seems that to bind to 0.0.0.0:80 address is behaviour for all servers, just tried with IIS, apache and SAMBA, all binds to IP which is set and additional to 0.0.0.0:80. I can't explain why it should be so but it is.

Then it's time for leew's suggestion, or decide for one of the two web servers.
If you currently only have one NIC with two IPs in the machine, you could give two NICs a try as well.

I decided to keep only one web server, I will try to host our portal on IIS, the main problem that from IIS 6.0, IIS does not allow to execute programs, for example code below get permission denied though our script and program to run has proper rights.  Anyway this question will be posted in new thread.

asp
<%
set objShell = Server.CreateObject( "WScript.Shell" )
objShell.Run( "programtorun.exe" )
%>

After digging information for three days eventually I have found that it is possible to bind two IP addresses to 80 Port. The links below describe how to do that if one web server is IIS.
