Hi, I have a very strange problem in my environment: - Windows 2003 Domain Controller - XP-Clients are in Windows-AD-Domain - RHEL2.1-Server with samba 2.2.12 - samba is configured in workgroup mode, not as domain-member I configured a share and 3 users. The users are created with the same user/passwords like the users use for login to the workstations. This are the symptoms: - if I run the UNC-Path for the share, an error pops up: "Extended error occured." (or something similar, my XP is a german version). No popup for username/password. - I can map a network drive if I put in "Connect as User". But, after a reboot, the network drive is gone. If I do not "Connect as User", the extended error pops up. - smbclient on linux works as expected I found some pointers, that "Simple Filesharing" can be a problem, so I disabled it - with no success. I would like to connect to network drives and UNC-Paths without entering a password. Are there any advices how I can solve this problem? thanks, Tobias
