I will doble check the tcp/ip config of the AS400 with the admin. The
problem is i know nothing about AS400 and y have to deal with an admin that
always found problems outside his responsabilitie area.
The telnet session is clean. No garbage or extra charters.
Thanks to point me to logging options. I will try this today at office. It
is exactly what i whas searching.
One more thing. the log files created by these settings are in serversbs.log
folder?

Thaks again
