We have an intranet site hosted locally, with a public URL in the form ofhttps://intranet.company.com. The site is added as a Local Intranet site by a group policy and all computers connected to the company domain have the setting "Automatic logon only to Intranet zone" (Internet Options - Security - Local Intranet - Custom Level - User Authentication), also by GP.
When the computers are connected to the company network, the site behaves as expected; the user's logon credentials are passed along and the site logs in. Other sites that the intranet links to, such as the company OWA or BI system, also work fine; the user starts IE9, is automatically logged on to the intranet, clicks on the link to the OWA and is logged on automatically with domain credentials from Windows. These sites all havehttps://site.company.com addresses and*.company.com is added to the list of local intranet sites by GP.
However, when a computer is outside the company network, the intranet does not load at all from within IE9 -- "Internet Explorer cannot display the webpage" is displayed instead. Using any other browser does not result in this error so the problem lies in the settings for IE9. I assume it has to do with the*.company.com entry in the Intranet site list because if I remove this entry the problem disappears. This is not an option though as I need that entry there to allow for automatic logon when connected internally.
Is there a simple way to have my cake and eat it too? I need the site to automatically log on users that are connected to the local network, but it needs to work externally as well. Even a prompt would suffice.
Appreciate all the help I can get here.
