A zone is a contiguous portion of the DNS namespace. It contains a series of records stored on a DNS server. Each zone is anchored at a specific domain node. However, zones are not domains. A DNS domain is a branch of the namespace, whereas a zone is a portion of the DNS namespace generally stored in a file, and can contain multiple domains. | |

Ok...a Domain, is a group of machines or hosts that share a common security permissions rules/database. For example...you could have 3 PCs... JOHN, MARY and ROBERT. And all of them are in the NAMES Domain. These 3 PCs share a common permission rules database and are in the same domain.
Also, DNS is a way of organize the several domains in a hirerchy structure (sorry for my english, is my second language) For example...you could put the domain LASTNAMES under NAMES domain and then, you should have a parent and a child domain:
(for example)
NAMES.com
LASTNAMES.NOMBRES.com
Windows2000 uses DNS as a simply way of put Domains togheter and all these records are stored on a DNS Zone, that its located in a DNS Server. DNS is like a sintax rules for Domains
Hope it will help.... | |

| What between a domain that you log into and a DNS Domain or a DNS zone.
Any good book on 216 should clearly tell you what each is.
Just remember a zone contains info about the domain. The domain is just the name space.
You can have sales.srv1.com and srv1.com in the one zone. Lets call it NYzone1. But just say i have another site in another state, i could create a 2nd zone, at this site which is a replica of the NYzone1. Why would i do this? because since it gets its name resolution info from NYzone1 clients can just access it locally instead of going back to the NYzone1 site for resolution which would take longer.
I used the 216 TK which explained it ok. | |

| Without complicating it, for DNS purposes, a domain and a zone is pretty much the same thing. It's only when you do fancy settings that it becomes somewhat of a challenge.
If i make a DNS domain of me.com, I am creating a zone file of me.com
In the zone file of me.com, i can place records such as www etc (to get www.me.com)
If i want to create now a subdomain (sub.me.com) i can use the same zone file of me.com and creating a subdomain entry. Or (here comes the complication) i can create a separate zone file now of sub.me.com
So without the fancy second part, the zone and domain on the DNS is the same thing. | |

| 216 TK is Microsoft's Windows 2000 Network Infrastructure Administration Training Kit 2nd edition. Now since reading it i wouldn't call it great, i give it 7/10. There are a few mistakes as usual. |
