OKay Guys I have a basic understanding of DNS.

However what I could use and explanation of is this...

In my forward lookup zones I have a Msdcs.domain.com .. under that it are folders.. DC, domains, pdc and BDC.. What are these and what function do they have?
Also inside my domain.com there are some folders called _sites,
_upp, _tcp etc...I think you get the picture..

Outside of A records and ptr records I'm kinda lost. Well I know what srv records and I believe these are linked to these "mysterious folders". But ahem.. Help me please

[useless comment]

Wow and windows are supposed to be the friendly way :lol:

I've never seen microsoft's DNS server but the way you describe it's configuration, it surely sounds far more complicated than BIND's or djbDNS'.. A real GUI nightmare :D

Actually from what I understand its rather a good MS tool.. I know some poeple hate MS but I mean.. The folders are there for a reason and alot of it has to do with Active directory. I'm just not sure on teh specifics.

They even have a dynamic DNS feature.. I'm not very clear on the security of it but the idea sounds good to me.

Yep each of those records are active directory objects registering in DNS..


I swear I don't know how to explain that better.....

its a nice interface, one thing about a GUI is it can prevent a mistake like in a flat textfile like named.conf ... but working with text file configs is easier IMHO..

thompsg good question and welcome to the party even I am Trying to figure out some records and Advance functionalities of DNS.

Lemme Share a few that I Know

_sites ,_udp, _tcp contains several critical information of all the root domain namespaces srv, ldap and kerboros records

srv (Server Locator Record) It is Created by default when you create an Active Directory Integrated Zone. This record point to the root parent dns server with in you domain.

ldap is a protocol provides information about and core functionality of Active Directory

kerboros is a the authentication protocol

dont worry about them first learn and get to know the diffrent kinds of dns records like

SOA ( Start of Authority)
NS (Name Server)
A (Host)
PTR (Pointer)
MX (Mail Exchange)
etc....


I recommend spend a lot of time in dns becos it is the most core service of any network operating system and even the internet !

Regarding Dynamic Update of DNS, Windows 2003 Supports two types of Dynamic Update of Host and PTR Records

1. Secure Dynamic
2. Secure and Non Secure Dyanamic

In Secure Dynamic Update all the member clients of an Domain can directly update the host and ptr records in the Root Primary Dns server by giving its ip address in the tcp/ip or by using an dhcp.

where as in Non Secure and Secure Dynamic Both members and non member of Domain can update their A (HOST) and Pointer (PTR) records.

Also Windows 2003 Introduces Stub Zones. A Stubzone is a Zone which contain only SOA and NS record which is usefull when there are many dns servers which are not clustered.


do try the following links

support.algx.net/cst/dns/dns2.html
www.isc.org/sw/bind/

I hope that I have helped you in some way !
