I am having problems setting up NT Challenge/Response authentication. I am running NT4.0 Server SP5, CF4.5.1 SP2 and all clients are IE4.01 or higher (this is an intranet application). The web server has a default web site which isn't used. The web server has a second website called home.companyname.com with a separate IP address. The pages in the website that do not have NT authentication enabled work fine (i.e. http://home.companyname.com/default.cfm works fine) so I know the web site is set up properly and the IP address is being resolved, etc. I have one page called login.cfm which has NT authentication enabled. The problem is that if I try to access http://home.companyname.com/login.cfm, the user is prompted with a security dialog box as if they couldn't be automatically authenticated. Interestingly, if I go to http://defaultservername/somedirectory/somedirectory/login.cfm, the user is not prompted and is logged in automatically. The login.cfm file is the same file (i.e. http://home.comapanyname.com/ has as it's home directory e:\inetpub\wwwroot\somedirectory\somedirectory\). I have enabled NT authentication on login.cfm via the default web site and via home.companyname.com. My current thinking is that it might be related to delegation. I know that when using NT authentication, the web server impersonates this user but since it doesn't know the password, the service can't access other resources on the network since the service can't authenticate to the other resource. But...if this is true, how do you enable NT authentication on servers hosting multiple websites. I must be missing something. Any help you could give would be much appreciated.
