Why can't I ping the server? (and how to fix it)

If you are used to using the ping command to test networks for connectivity and the presence of hosts, you be surprised to find that pinging a Windows Server 2003 Service Pack 1 computer sometimes won't work. That's because if Windows Firewall is running on the server, by default the firewall is configured to block ICMP Echo Request packets and other incoming ICMP traffic as well. You can allow the server to respond to ping requests by doing the following:|
1. Open Windows Firewall in Control Panel
2. Click the Advanced tab
3. Under ICMP, click Settings
4. Select the Allow Incoming Echo Request checkbox
Note that this problem doesn't occur with Windows XP Service Pack 2, which enables this exception by default.
