I will start out by saying that my knowledge of DNS is pretty limited but I understand the basics. Looking at our Windows Small Business Server 2003 system I see quite a few directories in our DNS and I was wondering if someone would take a look at the screenshot of our current DNS structure and see if it appears normal to them. See the attached screenshot. This is a small network of about 20 PCs and this is the only server which runs Active Directory, DNS and is mostly used for file & printer sharing. Since this is Small Business Server I have realized that everything with the setup is heavily based on wizards so maybe some of these things are just normal to SBS but I have been working with a Server 2008 Standard server and notice quite a few differences in the DNS structures for environments that are pretty similar. Maybe it is just the newer server OS though.
Our domain is NEA.local and I am not sure what the "standard" directories are in DNS but I thought it was kind of strange that we had two Forward Lookup Zones; one for our actual domain "NEA.local" and then another named "_msdcs.NEA.local". What is this Forward Lookup Zone used for?
Another thing I notice is all the entries for "Default-First-Site-Name"?
Where did this name come from or what is it referring to and why is it such a generic name?
Finally, the server is not running DHCP at this time; our RV042 router is handling that. About 6 months ago we changed all of our IP addressing on the network from 192.168.1.X to 192.168.5.x but looking around in the DNS I see that there is a Reverse Lookup Zone still in there for the 192.168.1.X subnet and not 192.168.5.X subnet. What is the best way to correct this? Is it safe to just delete the 192.168.1.X subnet and run through the "New Zone" wizard to set up a new one for the 192.168.5.X subnet? We aren't really experiencing any issues traversing the network really but I do notice as an admin that I cannot ping hardly any of the workstations expect 3 of them and I can only connect to the admin shares (\\SYSTEM\C$) on those 3 as well. The rest as far as pings don't exist on the network. Rather this has anything to do with DNS or DHCP I don't know but I would tend to think so. Would it be more beneficial to configure the server to manage DHCP as well?
I apologize for the rather vague questions on the DNS directories but I just haven't been able to find to much information through searching for what the purposes for all these directories are. They all seem to contain for the most part the same records. If anyone has any links they could share that explain the directories within DNS it would be greatly appreciated. Thanks in advance for any help.
