Re: Ping not working

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

  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.

  Thanks and have a nice day,

  Ahmed Nabil
