Hello, i use Red Hat Enterprise Linux ES release 4 (Nahant) with Samba Version 3.0.10-1.4E. Samba are running as PDC. If i save a 160 KB Excel file (Excel 2000 and XP) on a Windows 2000 Client, then samba hangs. With a XP Client running all normally. i make several tunning options (socket options, write raw,...) but no change. any idea? thx chris
