I am trying to lock it down a internal only website so only two Active Directory Security Group in our domain have access, and I cannot understand what I’m doing wrong. If the Active Directory User account is listed in one of the two Security Group the User gets access to the site and if the user is not listed in the group, they get routed to a custom Access Denied page. (Not the Windows Pop-up authentication box asking for the user ID and password) I guess I just don’t understand what I’m reading... (main thing is i don't want the windows pop-up) I'm very new to coding... I'm just a everyday Server/Exchange admin.
Any good examples someone can point me to? maybe a App_Start file, or something in the Global.asax
IIS 8 windows 2012 server
Using ASP Master Pages if that helps
