Q: I am trying to access the Site Settings of my SharePoint site, but I get a File Not Found error, although the rest of SharePoint works great. What should I do?
A: I recently deployed SharePoint Foundation to a server to run the System Center Service Manager 2012 portal, and I wanted to change the default site name. When I accessed Site Settings through the Site Actions menu, I received a File Not Found error (see screen shot below).
I
was using the fully qualified domain name (FQDN) to access the site. If
I used the NetBIOS name only (i.e.,
https://<server>:444/SMPortal), Site Settings worked without
incident.
The solution was an
Alternate Access Mapping was required for the Internal URL in addition
to the default https://<NetBIOS name>:444. Here’s how to add it:
- Access the SharePoint Central
Administration site, which is typically http://<server>:32736 but
could vary and should be listed under the Start menu, Microsoft
SharePoint 2010 Products, SharePoint 2010 Central Administration. - Select Application Management.
- Under Web Applications, select Configure alternate access mappings.
- Click the Add Internal URLs link (in the screen shot below, you can see I already added the FQDN at the bottom).
- For the Alternate Access Mapping
Collection, select Service Manager Portal, then enter the FQDN entry
(e.g., https://server.domain.com:444), then click Save (see the screen shot below).
Site Settings should now work when using the FQDN in the URL on the server.
