I'm trying to create a highly available pare of IIS servers to host IE 11 Enterprise mode. For this, I'd prefer to have the "site.xml" file stored on a network share so that it can be centrally managed. I've created a network share on a Server 2012 R2 box. Additionally, I have created a service account "svc_ie11ent" to run the Application Pools, with admin privileges on the share, NTFS permissions, as well as both IIS boxes.
The issue I'm encountering is that Windows Authentication doesn't work from another machine when webroot is on a network share. It does work if I use IE on the IIS server itself. If I move the webroot to the local file system of the IIS server, Windows Authentication works from the IIS server as well as another machine.
As a test, I changed the logon type for the website to use the service account, while still using Windows Authentication. This setup worked as far as basic IE browsing to the file, however it apparently breaks the actual IE Enterprise Mode functionality.
I also attempted disabling the loopback check, but that didn't provide any help. I'm open to any and all ideas!
