I'm going to be changing the IP address of my DNS/DHCP server on friday and
I just wanted to find out if there is anything to look out for? I attempted
this change last night(re-IPed from 10.65.6.60 to 10.65.6.84) and the dhcp
service ended up listening on .60 until I restarted it(which is fine..) but
then later it unauthorized itself..

I suspect there may have been a conflict in AD so I'm suspecting I'll need
to unauthorize before I re-IP.. then maybe reboot the host(to ensure all
services restart..) then re-authorize. How long should I allow between
authorizations? just typical AD replication?

The reason for the re-IP is I'm moving it into production and I want to
retain the same IP of the old dns/dhcp server.
 
RE: Changing IP of DHCP server

I think your plan sounds good. Let me know how it goes.
