Alright, I promise I won't put in any more threads regarding this nightmare. Let me rephrase my previous question. Is there *anyone* out there who has XP Pro systems successfully logging into Samba PDC's with Netscape Directory backends? I've rebuilt all components a few times and still I get the same behavior. XP Pro authenticates, begins the login process, and then the machine reboots. Win2k works fine. Did this with a default install as well as with the latest updates. Any info would be appreciated.
