I have a small LAN with SBS 2011 running DHCP and all of the sudden, none of the computers on the network can access www.aol.com
. If I disconnect the router and plug a PC directly into the cable modem I CAN access it so I know it is something internal. The config is such that there is a Linksys/Cisco router NOT running DHCP and then the SBS 2011 has DHCP and DNS.
I've looked at firewalls and tried turning them off to no avail. We've never entered any websites to be blocked in either the router or the SBS 2011.
I'm not really sure where else to look. Any suggestions?
