Hey guys, So, I just got my network reconfigured and Intervlan Routing set up with 6 different VLANs. The switch has DHCP enabled and configured and WAS issuing IP addresses to the devices. What SEEMS to be happening is when the lease expires for a...
Hey guys,

Thanks s...
okay, I removed all 8.8.8.8 ip address from the switch and only have 10.0.1.5 as anything Domain or DNS related. Let me check to see if I have Domain Communication back.
