What's the OS ? I seem to recall that Windows 7 changes some settings and disables file & printer sharing depending on the network type you are using from the network and sharing center. It should use Domain, or Home I think to enable File & Printer Sharing, which then enables ICMP (ping) responses.
Here's another post from an MS thread about someone having similar issues not being able to Ping their Win 7 computer, but all of their XP boxes fine. http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/cannot-ping-windows-7-machine-from-xp-machine/df2a921d-18e1-4197-a214-08142330f17b?page=1 Some text from the thread- "On my machine it was not a firewall issue. I had to go to the Networking Properties of the connection from Control Panel\All Control Panel Items\Network and Sharing Center and turn off AGN Filter Interface (64-bit)." ________________________________ From: Bill Monicher <[email protected]> To: NT System Admin Issues <[email protected]> Sent: Thursday, April 26, 2012 3:10 PM Subject: Unable to ping -- why? I have a single laptop in our department that I cannot ping. The user in question is able to access all network resources. Windows firewall is off, and no other firewall is running I have verified that all DHCP & DNS entries are correct. The user can ping anything on the network. Other symptoms: The machine loses connection to one server periodically. This is indicated by the fact that his computer shows the "offline" tray icon. Any time this happens, he can choose "synchronize", and he always is back online. He can access any internet/intranet site w/o problem at any time. Switch port counters show no problems. Changing switch port makes no difference. Any helpful suggestions appreciated.
