Today, I switched from Home Comcast internet service to Comcast Business with their hardware. Since the switch, I've been unable to access any of my end-points for Exchange 2010 and 2013. But the funny part, Microsoft Connectivity Analyzer shows Auto Discover, Outgoing and Incoming Pass.
At this point, not sure what else to do. Ports are open, Firewall disabled, ping successfully, internally everything works. Has of right not I'm posting this help topic from my network.
Help Please?
