change domain RRS feed

  • Question

  • my internal doamin is at this moment. I want to change it to
    Currently I have a mid size network with AD 2003, Exchange 2007, Office Communication Server2007, SQL 2008 etc. 

    I am planning to move into Win2008 and win7 soon. So it guess it is good time to resolve the domain name problem. 

    Can Anyone tell me how to do this

  • Thanks you for your blog, which is very helpful and clear but it emphasized on th SBS servers. I have already exchange 2007 and SharePoint 2007, Office Communications server 2007 R2 are running OK. I guess for SharePoint and Communication server, concern will be user's SIP changes as my TLD will be changed as well.

    My questions are:

    1. What actions I have to take in terms of already running Exchange 2007, SharePoint 2007 and Office Communications Server 2007 as I don't need to upgrad these servers?

    2. How about if we have a new forest which is the (xxx.local), set up trust between and xxx.local and then migrate machines from one to the other. if this work, then we will have less time presser.

    Many Thanks

  • Hello,

    Here's a tool for that purpose- Renaming your AD Domain. Personally, I would not do it unless it's absolutely necessary...

    Also, you are not going to give your TDL a .local extension but rather a public TDL?

  • Moving from .Local TDL to the Public TDL is the only intended outcome really as .Local TDL creates many unexpected trouble during SharePoint 2007 and Office Communication Server 2007 installation and this will continue to give trouble in future.

    As I mention before that we have Win2003 DC and AD, along with SharePoint 2007, and Communication Server 2007. At this time we are thinking to fix our TDL issue by going to have a public TDL.

    Miguel's post is helpful but this is clear what actions I have to take when I have Native AD mode with windows 2003. I have exchange 2007, SharePoint 2007, and communication server 2007, System Centre Essentials 2007 already installed.

  • Hello,

    it's not renaming the AD itself the problem, it's everything around it:
    -SMS (must reinstall)
    -SQL (windows account)
    -Windows services with domain account
    -Scheduled tasks with domain account

    I have found some blogs on domain rename:

    About exchange:

    Domain Rename - Rename a Windows 2003 Forest with Exchange 2003 installed

    Microsoft Exchange Server Domain Rename Fixup (XDR-Fixup)

    Supplemental steps for using the Exchange Server Domain Rename Fixup tool together with the Windows Server 2003 domain rename tools

    Hope this hepls to you to get the job done!

  • Yep. Like Lanista, I see a lot of cleanup work after the rename.

    It's so difficult to plan ahead and think of everything in a situation like this. If you can virtualize your network first as a test platform I recommend that... just so you can see what cleanup will consist of and better plan for the real thing. Testing it in a lab environment first is a lot more work but think about angry users and lost productivity and what a headache that can be!

  • Thanks Falcon,

    There are a lot of referrences not to procede renaming windows 2003 domain if you have exchange 2007 but all of those are couple of months old

    My question now is: Microsoft has not yet given the solutions to this trouble? I can't find anything in Microsoft site. If you know please tell me.
