AltLinux Server 4.0 + Samba-3.0.25 When joined to a Samba PDC, the XP x86_32 machine exhibits the following behavior: Select a folder, go to security options and hit 'add' to add a user. This brings up a dialog which reads: "The program cannot open the required dialog box because it cannot determine whether the computer named "server" is joined to a domain. Close this message, and try again." After which you see: "Unable to display the user selection dialog. This action is only valid for products that are currently installed."
