my sharepoint site in running port 80, with custom master page. Every thing works fine when I access with default url (http://servername/site/sitename/pages/home.aspx) .

but When I access the same site with alternate access mapped URL (portal.domain.com), cutom webpart works fine but all OOB feature stop working.

i.e. 1. Dropdown menu in global navigation does not work. 2. When i open any list or library, nothing display (but at same time i access the default url list/libraries showing data)

My findings:

  1. I am not able to open any SharePoint site directly from IIS (localhost:80, localhost:14552). It shows page not found 404 error.

  2. I not able to access any site via host name (servername:portNumber), to access any web application (Site), I need to mention whole url till site name at least (servername:portNumber/sites/sitename)

  3. I am using Http redirection to open the localhost to site url. and at the same time getting following error in event view.

Adding Screenshot of IIS binding...

Binding of Original Site enter image description here

Binding of extended site enter image description here

kindly suggest.....

  • So you have one http://servername web application in SP with AAM http://portal.domain.com configured. You did not extend the webapp in SP, just added an AAM, right? Q: What is port 14552? Q: How are bindings in IIS configured? Also could you please add some screenshots (webapps, AAM, bindings)? Feb 20, 2016 at 18:16

  • Thanks. I'm not sure IP Address can be empty in HTTP-bindings in IIS. Q: Do you plan to stay within extended web app model, or revert back to simple AAM-only method? Q: Do you need to map single http://servername/site/sitename/ site collection to http://portal.domain.com/, or whole http://servername webapp to http://portal.domain.com like in pre-HNSC times?

  • 1. IIS Binding.. should I add server IP address ! 2. As I mentioned we tried first with AAM then we opted to Extened WA. so we can go back to AAM if problem is resolved, 3. we need to map only single site collection with AAM address.

You didn't specify how 'HTTP redirection' you mentioned is configured, but https://support.microsoft.com/en-us/kb/2818415 is a very nice article that explains url rewrites - both symmetrical (http://srv1/sites/site1 -> http://srv2/sites/site1) and asymmetrical (http://srv1/sites/site1 -> http://srv2/s1)

If you want to be able to access http://servername/site/sitename/ site collection by http://portal.domain.com/ address, that's not quite AAM thing, but something covered by HNSC feature. Please take a look at this article https://technet.microsoft.com/en-us/library/cc424952.aspx ('Convert path-based site collections to host-named site collections' section)
