I am running samba 3.0alpha17 as an NT PDC on solaris 2.8. When I attempt to join the domain with a win2k system, I receive the following error msg: The following error occurred attempting to join the domain "ENG-2K": There is no user session key for the specified logon session. I am using a valid user ID, with correct password that has permissions to join domain, and have reset the machine account password.
