I currently have a Samba 3 PDC. Everything seems to work, except IE/Firefox both bring up a prompt for username and password. I'm using the exact same config files from another setup that worked fine. You for some reason can't type in just the username and password, like you would think. For example, my workgroup is 01Networks, and even though the XP Pro machine is logged in sucessfully with that same name, unless I type in 01Networks/adam and password, the prompts never go away. After I type those in they work. Why is this setup acting strange after a previous setup done exactly the same way works fine? Also, why would I be required to put in my Domain/User instead of just User when normally I only ever needed User? Also normally IE/Firefox just sent out my info.
