I installed/compiled Samba 2.2.1 on AIX ver. 4.3.3. it is running ok. It took 189 minutes to copy a file (outlook.pst) 404 MB to the AIX f50 server . I modified the smb.conf file, and it did not help. Your input is really appriciated. Aziz -------------- next part -------------- A non-text attachment was scrubbed...
