Recently began setting up my own personal production and test networks on my personal VM host (VMware Esxi 5.1). I had purchased a domain from GoDaddy and planed on using "internal.domain.com".
Shortly after setting up the first Domain Controller realized I need to change my NetBois to allow login as domain\user instead of internal\user.
Some quick Google searching provided the following resource:

Step 1: Access Domain Controller
Step 2: Open a command prompt
- Start > Run > cmd
Step 3: Generate Domainlist.xml
- From command prompt enter "rendom /list"
- 2008R2 directory: C:\users\[logged in user]
- From command prompt enter "type domainlist.xml"
- Browse to file location
- 2008R2 directory: C:\users\[logged in user]
- Right-click and select edit (use favorite text editor if prompted)
- Locate <!--ForestRoot -->
- Change NetBiosName value from current (internal) to desired (domain)
- Note I only wanted to change login from internal\user to domain\user if you wish to change domain completely update all instances of old value to new desired value.
- From command prompt enter "rendom /showforest"
- Verify results
- For domain login ensure FlatName is what you want
- For entire rename ensure correct values for all fields
- From command prompt enter "rendom /upload"
- From command prompt enter "rendom /prepare"
- Best practice is to ensure all domain controllers have firewall off for remainder of operation
- From command prompt enter "rendom /execute"
- Verify no errors on results if so resolve before continuing (issue I ran into was firewall issues)
- Note Domain Controllers may begin restarting.
