Due to security concern, by default you are not able to Ping a Windows Server 2008 machine. At first I though there is a problem with my network but actually it’s disabled. To enabled Ping reply from Windows Server 2008, goto Window Firewall with Advance Settings from Administrator Tools menu.
Look inside Inbound Rules, scroll down to File and Printer Sharing, right click and enable this rule. (pic below)
After that the check icon will turn green
For Windows Server Core which does not have any UI, you can enable this rule from the command prompt.
I have received numerous emails asking how to update the regional settings in a GPO or how to make the red line turn green.
If you are here then you know this red line.
F5: Mark all settings on the page as “green” (apply all) F6: Mark current settings on the page as “green” (apply this settings) F7: Mark current settings as “red” (don’t apply this setting) F8: Marks all settings on the page as “red” (don’t apply)
