Hi. I have a problem when I use Integrated authentication mode. It works well for all the clients except the ones that are in stand alone mode, so no domain validate the users when they startup their machines. The problem with this is that when i try to open a web page it prompt me for username and password. It is fine if it does it one time or when i open a new window of internet explorer, but it prompt me for user and password any time i move from one page to another. someone knows the reason for this problem? It affects me in my MAC Clients that doesn't validate in a domain when they turn on the machines.
