Question: Having some intermittent internet connectivity issues. I have a dsl router/modem connected to my internal network. I have a switch with several computers connected. Two servers connected to my switch. Ethernet cable running from dsl modem/router to the switch. All has worked well for several years. When I do a diagnostic on the router, it fails the gateway and dns part of the test. What does that mean?
I have my domain controller pointing to the router - the router is the gateway out to the internet. If the router is failing the gateway test does this mean the router is bad?
The router is only routing out to the internet. No dhcp or dns. My domain controller (windows 2003 server) is doing all of that.
I'd also check the inside interface of the DSL modem to make sure that the gateway/dns your server thinks is the right gateway/dns--is actually programmed on the DSL router inside interface.
