Is it always the same IP having the issue? If it's happening from lots of different IPs, there may be an issue. If it's the same user each time, they may just have a bad client.
yess, this happens from different connections. even from different DSL connections to the server.
i can 171 occurrences in my log file now
i don't know wt to do to trace the exception generator!! is it sthg concerning IE? or nthg to do with IE?
