This one has been a killer. About 3 weeks ago Comcast replaced their router which caused me to resubnet this network. I didn't think it would be hard. One Server, Twent workstation (DHCP) and three static IP printers.

Something still isn't right. At 6pm something happens that causes a network disconnect on a couple of different workstatons. Something similar to pulling the network cable. Apps are hung and nothing responds. It started out being a IPV6 issue when Comcast left their IPV6 DHCP running and that wreaked havoc. Finally got it shut off but still have weird things happening.

I have a little workstation inventory program that times out trying to connect to the workstations. So... I tried a tracert to the workstations and it times out! No matter what workstation I try a tracert to it goest through 30 steps and times out. dcdiag says everything is fine but it isn't. ANyone have any ideas?

Is it safe to un-install and re-install the DNS role from the server?
