I moved the question to here from stackoverflow.com
I am trying to configure a IIS 6.0/Windows Server 2003 web server with a ASP.net application.
When I try to ping the server from client computer A I get the following:
PING 74.208.192.xxx ==> Ping fails PING 74.208.192.xxx:80 ==> Ping succeeds!
From client computer B, BOTH the pings fail.
PING 74.208.192.xxx ==> Ping fails PING 74.208.192.xxx:80 ==> Ping fails with a message "Ping request could not find host 74.208.192.xxx:80"
Both clients A and B are on the same subnet. The server is outside (a virtual server hosted by an ISP)
I have an ASP.NET application in a virtual directory on the server. In IE or firefox, if I enter
http://74.208.192.xxx/subdir/subdir/../Default.aspx, it works from both the clients!
The server has default firewall settings but web server enabled (Port 80 is open).
From client A (note the different 'reply to' address when the ping succeeds.

From client B

Please check the name and try again.
My main problem is I have a web service (asmx) file and the web service client program is not able to access it from client B, but able to access it from client A. I am trying to find out why and thought this ping issue may shed some light.
I can ping yahoo.com both the computers.
