Seeing as the clients can't presently reach the mail server in the first place, I have the sneaking suspicion something else is wrong. Tiks, you mention can ping the mail server through the ISA server.. do you mean from the ISA server to the mail server ? As I said, some more information might be handy. :) ________________________________ Van: Ergun ANIL [mailto:Ergun.anil@xxxxxxxxxx] Verzonden: di 17-1-2006 14:53 Aan: [ISAserver.org Discussion List] Onderwerp: [isalist] RE: How do I enable PING for clients through my ISA ? http://www.ISAserver.org Hi and good day, As I know You must create Access Rule on ISA SERVER for ping.
