Intranet problems with Internet Explorer 11
You might experience the following issues with your intranet site, after upgrading to the latest version of Internet Explorer.
Internet Explorer 11 works differently with search, based on whether your organization is domain-joined.
Domain-joined computers. A single word entry is treated as a search term. However, IE11 also checks for available intranet sites and offers matches through the Notification bar. If you select Yes from the Notification bar to navigate to the intranet site, IE11 associates that word with the site so that the next time you type in the intranet site name, inline auto-complete will resolve to the intranet site address.
Non-domain-joined computers. A single word entry is treated as an intranet site. However, if the term doesn't resolve to a site, IE11 then treats the entry as a search term and opens your default search provider.
To explicitly go to an intranet site, regardless of the environment, users can type either a trailing slash, like" contoso/", or the http:// prefix. Either of these will cause IE11 to treat the entry as an intranet search.
You can change the default behavior so that IE11 treats your single word entry in the address bar as an intranet site, regardless of your environment.
To enable single-word intranet search
Open Internet Explorer for the desktop, click the Tools menu, and then click Internet Options.
Click Advanced, check the Go to an intranet site for a single word entry in the Address bar box, and then click OK.
If you'd like your entire organization to have single word entries default to an intranet site, you can turn on the Go to an intranet site for a single word entry in the Address bar Group Policy. With this policy turned on, a search for “contoso” automatically resolves to http://contoso.
