			===Network Troubleshoot===
			Info from: http://www.petri.co.il/csc_how_to_use_the_osi_model_to_troubleshoot_networks.htm

			Bottom up approach:
			*Is your network cable plugged in? (physical)
			*Is there a link light on the Ethernet switch and Ethernet NIC? (data-link)
			*Do you have an IP address? (network)
			*Can you ping your default gateway? (network, testing LAN IP connectivity)
			*Do you have DNS server information?
			*Can you ping your DNS server? (network, testing IP connectivity)
			*Do you have a firewall configured? (network on up to application)
			*Can you ping the host you are trying to get to by name? (application, DNS and network WAN IP connectivity)
			*What format is the graphic in? Do you have a viewer for that format? (presentation)
			*Can your web browser open up another website? (basic application troubleshooting)
