Hi, Since upgrading to about 3.0alpha24 from alpha23, workstations in a samba domain can't access shares on other workstations. They can access the domain controller fine. The workstations are XPsp1. they have all joined the domain without a problem, although that was under alpha23. I have made the security policy changes suggested, which is what allowed me to join the domain. The errors I'm getting look like this (on the workstation with the share I want to access).

All workstations are domain members. Any suggestions? James
