Still testing 3.0.23pre1... Tried to add a user to an ACL on a share \\exdev\bufs. EXDEV (3.0.23pre1, AIX5.3) trusts ACDEV (3.0.21c AIX5.2). share connected to WinXP-SP1 (not joined to a domain). Same config file as when exdev ran 3.0.21c which was ok. Receive error: "The program cannot open the required dialog box because it cannot determine whether the computer named "exdev" is joined to a domain." <clicks close> "Unable to display the user selection dialog. The system cannot find message for the message number 0x%1 in the message file for %2." <clicks ok> -- Suggestions? Who wants a log level 10? (This might be related to the other problem Volker is already looking into with winbindd and SIDs.) :-) Cheers, Bill
