We are in the process of getting another ISP in our office. The purpose is to get a faster speed and also setup a failover at a later time with the slower connection. We have a windows server r2 2008 that is the domain and DNS for our network. At this time, I have both internet connections plugged into our network via a switch. Our original ISP connection is on a router with 192.168.1.1 and the new ISP is on another router with 192.168.1.254. The domain/DNS is on 192.168.1.2 and has its gateway set to 192.168.1.1
I currently have my PC statically assigned to go to .254 for the gateway and .2 for the DNS. I want to move all of the other PC's over to this connection tomorrow. I want to make sure that I am not over-simplifying my next move. It seems to me that I should be able change the DNS servers gateway to 192.168.1.254, then have all users log off the domain and log back on and their PC should get a dynamic address and the DNS should automatically rout their traffic to the .254 gateway.
Am I right n assuming this, or am I missing some steps that will affect this transition?
