OK Did you say this only happens on the odd occasion? does it fix itself, how long till it fixes itself? So the ISA can definitely resolve the what you've got in the "upstream proxy settings" correctly.. Is there a specific error message/number you get you can look up Have you got a hosts file which references the "upstream proxy" by any chance Other than that I do remember something about settings the dns ttl to 0, but im not going to got here in this state i'm out.. might be a job for super Jim!!

I cannot understand how this could be happening. Can you explain how this could happen when I have a single Nic proxy that is not the default gateway? ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Visit TechGenix.com for more information about our other sites: http://www.techgenix.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: greg@xxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=isalist Report abuse to listadmin@xxxxxxxxxxxxx
