Can anyone give some details regarding the message : The following error occured while joining the domain "DOMAIN" The procedure number is out of range. This message appeares only in win XP Pro / win2k clients, the 98 lients work ok. I tryed various versions of Samba (2.2.8, 2.2.6 and now 2.2.0) and I was getting the same error. The win XP is correctly patched (registry). The Wins / File Sharing works quite fine.
