    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

    Sorry Si not with you. Do you mean a single level domain?

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

    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. :) :wink:

    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.

    Ahh with you now.

    At our school the domain is call oundleschool.local. This is purely an internal thing and has no internet presence at all.

    The Schools presence on the net can be found at www.oundleschool.org.uk

    This is hosted I think by Demeon.net?

    Does this help? :?

    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 :scratch

    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.
