Please note this Question is **NOT** about a production environment. It is about a training/learning environment I am using to go thru a MS Press textbook to get my SBS 2008 MS Certification. Hence phrases like "best practices" are irrelevant.
Also although I know a great deal about the MS "home" OS's (If fix PCs for a living), I know NOTHING about SBS 2008 except how to install it and answer some required installation questions so please spell your answers out in detail. Do NOT assume I know the basics, I do NOT know the basics (yet).
QUESTION: What are the plus's and minus's (especially the minus's) of NOT enabling DHCP server on the SBS 2008 PC.
My entire network is ONE client PC connected to a router (connected to a Comcast modem) and a SBS 2008 PC (used as a server) connected to the same router PLUS a roommates PC connected wirelessly to the same router.
My concern in enabling DHCP server on SBS 2008 is that decision impacts my business PC and my roommates PC. Example. My ISP has an outage that it later recovers from. In my experience I often need to powercycle BOTH the modem and the router to recover after the outage is over. If the SBS 2008 PC is the DHCP server **HOW** do I use it to reassign the ip addresses. I mean please provide a fairly detailed step by step answer for two cases below.
Also I believe (but am not sure) that the ip addresses are on "lease" and must be anto-renewed every 24 hours. Will that require case (B) below (always leaving the SBS 2008 PC on) as the always-on router will no longer be doing that.
(A) My SBS 2008 PC is ONLY on when I want to move thru the text book and learn more. i.e it is usually off (example during the ISP outage and recovery).
(B) My SBS 2008 PC is ALWAYS on except for reboots for updates and occasional other needs.
I am listing (B) as I would not be surprised if you answer that making the SBS 2008 PC the DHCP server is not very practical unless the server is ALWAYS on (or close).
