I have a question about single-label domain in a windows 2000 network.

What are the implications of using a using a single-label domain within a windows 2000 network (for example, network , bank, companyname). Issues such as DNS registration and name resolution.

Thanks in advance, SimonV

 

I mean such as using "certforums" instead of "certforums.co.uk" for the domain name.

 

My home domain is just a single label domain and i have never had a problem

 

I think a single-level domain like "certforums" simply would not refer to any higher level domains. Subdomains would be something like:

bank.certforums
network.certforums

and such. Extended levels such as co. and uk are top level domains and of course, root (.) is at the top of the heap and points to domains and subdomains responsible for lower-level zones.

Now Phil will come along and set me straight, I'm sure.

 

Aww trip, I'm not about to do any such thing

 

I've been thinking about this, with regards to my own Lab domain.

When prompted for a domain name I entered "Surname" (obviously using my, er, surname).

Now, without me doing anything else, all Users' and computer FQDNs automatically appear as .surname.com, eg

Server2.surname.com, or user1.surname.com

I thought this was natural, until I discovered, that at certain times online, DNS was resolving my Lab to someone who did actually hold that domain name.

I don't think I really know what I'm saying, or clearly can't make sense of it, but I thought I'd throw it into the pot anyway.

 

Gav, that comment is just ASKING for it,

But nice guy that I am, I won't say anything, mainly coz I don't really know either!

 

Just thought I'd let you know what I found out about this, it seems that using a single-label domain like companyname instead of companyname.local can have an impact on dynamic registration of DNS records but only if SP4 is installed. With SP4 installed you will not be able to dynamically register your records on this type of zone without a registry hack.

So bearing in mind my mindless rantings above, does that mean I should have called my domain "surname.local" then ?

'scuse the ignorance, I'm having a blonde weekend - even though I'm actually learning more than usual

 

The reason I asked this question is that the school has a single label domain that was setup before I came. After the problems I had lastweek with the system state restore episode I was looking back throught the event log and came across:

Event ID: 5781
Source: NETLOGON
Description: Dynamic registration or deregistration of one or more DNS records failed because no DNS servers are available.

and after more investigation I found that dynamic updates were not being performed by Windows 2000 Service Pack 4 (SP4) members. This brought about the single label domain question. Now my next question is what course of action to take next.

My choices are:

1. Do nothing
2. Apply the Registry hack to the PC's on the LAN
3. Change the name used for the networks domain

Comments welcome,

SimonV

 

My choice would be to mod the registry on the PC's. I'd rather fix the problem than do nothing and changing the domain name will involve removing the domain then creating a new Domain fom scratch. Depends how much overtime you want

It should be fairly straight forward to script the registry changes required and set it to run in a startup script for Domain Computers.

 

OK I applied the Registry hack to a test PC and everyting is fine, Phil can I ask you about making a script:

Any help on this would be great.

Is the registry hack the following ?

 

Yes Phil, it doesnt exist so need to be created.

Si

 

Ok, Ill have a play later and come back to you

 

Give this a whirl

 

Phil, worked a treat. You are the Script Master

Thanks for taking the time to do this.

Si

 

No Probs are you just going to bung it in a startup script ?
