How will changing the gateway address on server r2 2008 affect DNS and domain
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?
