Yes, I think that'd be very useful; when a user has a repeatable network problem, we could have them turn this on and create a detailed log file for us. In cases of reset connections, etc, this would be quite useful. Doesn't TCPDEBUG do something like that already, though? I haven't taken a look into it, perhaps I should. Mike "Silby" Silbersack
