Help! I Cannot Login to My SharePoint Site Using the Host Header Name on My Server.

Scott ZischerkIf you’re trying to access your SharePoint site via a host header from your SharePoint server you may encounter a series of login prompts followed by a blank screen.  To remedy this, you can either make the site available on another port, or you can add a registry setting.  This is how you would add the registry setting:

  1. Open Regedit.exe
  2. Navigate to: HKLM\System\CurrentControlSet\Control\Lsa\MSV1_0
  3. Create a Multi string value key with name BackConnectionHostNames.
  4. Add SharePoint Web Application Host-Header Name as the value to this key (without the protocol http://)

That’s it, try navigating to the site via the host header and log in again and it should take you right in this time.
