I have a wireless router setup in my network that is set to go out through my ISA server. I have customers who come into the office and need to be able to access the internet. Most of the time when they connect to the wireless router and try to access the Internet, they get a login prompt at which time they enter a valid user name and password on the network and then they are able to access the Internet. I have one customer though who is trying to access a secure site on the Internet through this wireless connection and they are not prompted to login. The one time they were prompted to login in, they were still denied access by the ISA server. I don't know what I need to be checking to make this work. Can someone please help me.
