This is not really a programming question, but I am at my wit's end ...

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).
