  • How to change a domain Name ???

    Hi everyone,

    to explain the situation : I have two different companies , each one with it's own WIN2003 and Exchange2003 , each one with it's own domain name.

    how can I migrate the Exchange addresses of one company to the second one so that it'll be with the same email domain ? do i need to migrate and rename AD ?

    if i do , where do i find the info of how to do that ?

    thanks in advanced for your patience...

    Just a few points to consider and questions to be answered that will help with you getting the correct response.

    How many users are we looking at?
    Will emails from the Company being moved need to remain active whilst allocating them the other company's email address?
    Research in to Forest Trusts?
    Have you any legacy software or NT boxes? This will determine whether Forest Trusts are feasible.
    Do you need security isolation for each company?
    Will they come under one overall Head of company?
    Other considerations would be where your IT staff will be located and what level of access will be granted etc etc.

    The way to go about it will also depend on your timescale for project completion, the resources to be accessed by each company and the number of users - being whether you need to migrate or just recreate a domain tree in the other Company's Forest from Scratch and maybe script user creation etc and maybe have a parallel domain whilst moving computers over.

    You could also consider, though I am not an expert so this will need clarification from Simon, adding the external domain for the other company to the other Exchange organisation, so it will accept emails for that domain and then point the MX record to the Public IP address of the other Company's email. You could then consider setting up contacts in AD and have mail forward to the other Company's User's mailboxes for the time being and will allow you to allocate an email for the other Company at the same time, so in effect, they have two emails addresses for both Company's during the transition. The outside world will only see one company if you then only advertise the one email.

    Forest Trusts will then enable you to share each others resources depending whether this is feasible as both need to be in Windows 2003 Native mode at Forest level. No legacy software or NT servers can then exist on the network.

      The WINDOWS domain name has no connecting to the SMTP/EMAIL domain.
      Therefore if you want to move users to another WINDOWS domain then you can. Simply configure the SMTP domains, email addresses and user accounts on the new server correctly, change the MX records to point to the new server and then migrate the data.
      You do not have to do anything with the WINDOWS domain.

        hi Guys,

        first of all , thank u very much for the answers !!!

        Simon , what i need is to register the old domain in the new DNS server or the other way around ?

        i need to transfer all the users (actually only 20) from the old mail domain( alisia.com in that case) to the new one ( manpower.com ) . i need to change the DNS server in Alisia site or in Manpower site ?

        Thanks allot...

          The email domain has nothing to do with the DNS servers of the server. Exchange doesn't care about internal DNS.

          Therefore the only thing you have to do is ensure that the EXTERNAL DNS is configured for that domain to point to the Exchange server and that Exchange has been configured to accept email for that domain. Then the required email addresses are on the user accounts. No changes need to be made to the internal DNS at all.
