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 DNS 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 if something "goes wrong" with my SBS 2008 PC, and I have a half hour before a customer job to do internet research AND I find I cannot resolve DNS addresses UNTIL I fix the problem on my SBS 2008 PC then I may loose the job fee. And my roommate also has his own business and will have the same problem.
The correct answer is NOT: Well anyone who knows anything about SBS 2008 knows how to fix that on their SBS 2008 PC because I know NOTHING about SBS 2008 except how to install it. Example. The solution (restore DNS services) is in Chapter 5 of my MS press textbook but I have ONLY got thru Chapter 3.
SUMMARY: When I bought a hi-end Windows 7 PC to act as a SBS 2008 server (i.e dual boot) and paid MS technet $200 for the license I did not know that learning SBS 2008 might impactt my own and my roommates **PRODUCTION** PCs. I believe that making the SBS 2008 PC the DNS server may very well do that.
Also I assume (Please explicitly answer this) if I make the SBS 2008 PC the DNS server I assume that at a minimum I must leave it on all the time (except for occasional reboots for updates and other needs). Well, guess what, I was NOT planing on doing that. I was only going to turn it on when I wanted to learn more about SBS 2008. PLease confirm that it must always be on (or close) if it is the DNS server.
Your answers to the above questions will help me understand this more and what my options are.
