Rename Server 2003 domain to avoid "single label domain" error when migrating to server 2008?
Posted on 2012-04-10
I have inherited a very odd top level domain of SQ.SpeedyQuote
There is only one DC and it is Windows Server 2003 Standard SP2. (server1.SQ.SpeedyQuote)
The previous sysadmin tried to migrate it to a new Server 2008 R2 and failed.
The error message he couldn't get past said he could not continue because it was a "single label domain name". I was under the impression that if you had a period in the domain name anywhere, even if its "SQ.SpeedyQuote" that it is not a single label name, it just has a really awkward top level name (instead of .local at the end). To be safe (and make my domain look normal) I was considering using the domain rename toolkit for server 2003 and adding .local to the end of it. I was wondering how risky it is to use the tool or how well it works. If I were to use it, am I missing any steps? :
1. Raise Domain and Forest Functional Level to Server 2003 (they both already are)
2. run "rendom /list" then "copy domainlist.xml domainlist-save.xml"
3. Modify domainlist.xml and change all instances of the domain name and save
4. run "rendom /upload" then "rendom /prepare" then "rendom /execute"
5. reboot server
6. run "rendom /end"
please share any tips or warnings about things you've encountered that went wrong during a domain rename using rendom and a suggestion of if you believe it is necessary or a good idea.
