I have two domain controllers (DC1 and DC2) for one AD domain. only DC1 running IAS to provide Radius Authentication for network elements.
Radius authentication works fine against this server.
IMy problem is that IF DC01 fails we loose radius
question 1 how easy would it be to get Radius on the second DC if the first fails
question 2 now that i think about the network elemets (switches , firewall, etc) are pointing to the radius on DC1, so thye would all need to be changed.
whats the best way to to go about this?
