Site Collections Display 404 Not Found

Question

Dear All

I have considered our SharePoint environment to work with multiple site collections called Staff, Students and Parents and so the internal URLs look something like http://sp (for the top level site), http://sp/sites/Staff, http://sp/sites/Students, http://sp/sites/Parents. I can navigate to those pages and they work correctly.

The people who manage our firewall have just made the necessary DNS changes to enable our long address to work with our SharePoint site so instead of the above you can use http://sp.mylongaddress.co.uk (for the top level site) and http://sp.mylongaddress.co.uk/sites/Staff etc etc. The top level site address works correctly but when I navigate to the site collections, they all show a "404 Not Found" error message.

Please could you give me some ideas about what might be wrong? Is there something else that I should have configured for the site collections? As it's possible to reach the top-level site, I don't think it can be an issue related to the firewall.

I would be really grateful for you ideas

Best regards

Daniel

Answer 1

Hi Daniel,

If you have not already done so, you need to go into Central Admin, go to the Alternate Access Mappings configuration screen (under "Application Management"), and add the URL "http://sp.mylongaddress.co.uk" to one of the additional zone (Intranet, Extranet, etc) fields.  IIS can handle the connection to the root site, but without this information added, SharePoint cannot properly handle the requests to your other site collections.
