MessageHi , actually after the new threat of welichia , many ISP's started turrning of the ICMP on many links , so the ping and traceroute using firewalls or accesslist , also they blocked many ports such as 135 , the one used by Blaster and Welichia , so to check wheather it is an ISA problem or not , try to ping something outside the boundary of your ISP from the router , if you can't this means that the ICMP is bloked regards ----- Original Message ----- From: Nabil, Ahmed To: [ISAserver.org Discussion List] Sent: Wednesday, September 03, 2003 7:57 AM Subject: [isalist] Ping not working http://www.ISAserver.org Hi All, My Network clients are able to browse anything on the internet from their browser (Yahoo.com, ........etc), yet when you try to ping www.yahoo.com from the command prompt you get an Request time out message. I believe its ICMP port. What do you think ? Please advice.
