I have used PingPlotter for maybe a year now and although I am not a network guru, it has been useful. For some reason, no I can't ping outside of the network anymore. I installed Office 2007 2 days ago and ESET Smart Security 4.0 yesterday. That's the only software changes I know of. I contacted ESET and they showed me how to set an exception for PingPlotter. Any one know why I can't ping outside of the local network?
