Dinamically adding multiple identities (hostnames) to a IIS WebSite

Posted on 2008-06-13
Last Modified: 2013-12-17
Hi, below is a part of a code to create a new IIS website on C#.
The code works perfectly.
I need to put multiple identities on the "ServerBindings" property.
I want that the website will be available on 2 hostnames ( and

I tried to do:
site.Invoke("Put", "ServerBindings", string.Format(":80:{0},:80:www.{0}", website_name));
(to put the website_name and www.website_name port 80)
like the way that I see on the MetaBase Explorer (IIS resource kit) but it doesn't work.
DirectoryEntry site = (DirectoryEntry)root.Invoke("Create", "IIsWebServer", random_site_id);
site.Invoke("Put", "ServerComment", website_name);
site.Invoke("Put", "KeyType", "IIsWebServer");
site.Invoke("Put", "ServerBindings", string.Format(":80:{0}", website_name));

can't speak much about c#, but from what I can tell you are trying to treat the serverbindigs property like a plain string(?)

This property is actually an array of strings, so you will need to first retrieve the existing array, then append the new value and then set that new array back to the property.

Cheers,  Mike.

I can offer these bits of code.  The first script simply lists the web site properties as an xml formatted page.  Call it like this:


(where server is the name of the web server, and siteid is the site ID from the metabase)

Use this script as input to write data into your html form - they are output as a comma delimited string like:


the second script takes the serverbindings array from a form field named "" and writes it to the metabase.  The url is the same format as above (e.g. http://webserver/path/updatehostheaders.asp?server=localhost&siteid=1)

hope that helps a bit.
