Just for refernece, Dominic brought this up in an earlier thread: http://www.freebsd.org/cgi/mid.cgi?2DE61B0869B7484997BCA012845482C7EBE62DDD88@WIN2008.Domnt.abi.ca and at least on other person seems to have the same issue... quick question for you Dominic, do you see the correct number of routes, but a new wrong one appear? or does the route just simply disapear? or does a new one seem to replace the old one? The reason I ask is that if a new wrong one appears, it could be memory corruption, but if a new one replaces the old one, for some reason when allocating a new route, it could accidentatlly be replacing the default route... Just some thoughts... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
