Iroqouiz Posted December 18, 2013 Report post Posted December 18, 2013 Yes, it is relevant to the IE setting, IE default security setting is Automatic logon only in intranet zone. If I add catalog server to intranet zone, it works well. But in SCCM client settings, it only adds app catalog website point to trusted sites zone. so login dialog box prompt. How to setting for it? Create a GPO to add the site to everyone's intranet zone. Quote Share this post Link to post Share on other sites More sharing options...
