I have an issue with Windows 7 computers intermittinly losing Internet connections. All the XP units hold the connection, but Windows 7 units will lose connectitiy randomly. When this occurs, I can still access the network and shared drive files as well as our internally hosted website, but no outside Internet access. I have tried putting in static ip and dns addresses, releaseing and resetting the IP address, disableing and enabling the network adapter and flushing dns. The access will be out for a while and then come back. The issue still occurs.
