one client with window 7 in domain enviroment.unable to ping from other clients. even from server.Firewall problem.I don't wanna turn off firewall completely. i want to put exception for only one service .Which one should i do?

Run this one: runas /user:Administrator " netsh advfirewall firewall add rule name=\ICMP Allow incoming V4 echo request\ protocol=icmpv4:8,any dir=in action=allow" Other examples: http://support.microsoft.com/kb/947709 Or enter "Control Panel -> Windows Firewall -> Advanced settings" and enter the rule allowing incoming ICMP. --- Paul Svirin StarWind Software developer ( http://www.starwindsoftware.com )
