Ping Windows 2008 with Firewall On

You should be trying hard to keep the firewall on when deploying Windows Server 2008.  If you need to ping the server and haven’t enabled File and Printer Sharing, then open Windows Firewall with Advanced Security and under Inbound rules, enable “File and Printer Sharing (Echo Request – ICMPv4-In)”.  Might as well enable ICMPv6 while your at it.
