We have a WSS3 sharepoint server named ServerA.
We want add ServerB as the alias name. If we just add additional A recordwith same IP in to the DNS record, some form submit will prompt error. Such as

Exception: The Web application at http://serverB could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application.

Any idea how to have two host name for one server?
Thank you.

    You need to add an alternate access mapping to the web application in Central Admin, and you need to also add a host header entry to the site in IIS.

    I want to keep both host name, serverA and serverB.
    When i do alternate access mapping to the web application in Central Admin, the serverA will be replaced by serverB. User can not user http://serverA to access web site.

    Accepted Solution

    False.  You need to add serverB into another zone (e.g. Intranet) on the web application.  This is done by Editing the public URL's on your web app.
