(no recursion) through the ISA server. - The ISA is has protocol rule set for DNS Query allow. and packet filter for DNS lookup. - I want to be able to resolve names using NSlookup from my clients. It does not work. Any ideas would be appreciated. karzon ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: david@xxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
