One of the most common ways for an administrator to see if a particular server is up or not is to send an ICMP package to the server or to Ping it. This is also called an Echo Request.
Windows Server 2008 disable this Echo Request by default. Here's how you can turn this on:
1. Open Server Manager
2. Expand Configuration section
3. Expand Windows Firewall with Advanced Security (OK, Microsoft, is there a Basic one???)
4. Click on Inbound Rules
5. In the middle pane, scroll down and find "File and Printer Sharing (Echo Request - ICMPvX-in)" where the X stands for the IP version number
6. Right click it and select Enable
7. If you want to edit advanced options then right click it and select Properties option instead
If you are running the core version, you can accomplish the same thing by issuing the netsh command:
netsh firewall set icmpsetting 8
