I'll be migrated one of my client Domain Controllers from Windows 2000 server to Windows Server 2008 R2. Their current internal domain is using .COM, their registered domain name is .COM also therefore, the internal domain and the external domain are identical.
The issue for now right now is when you try to resolve the internal domain name using NSLOOKUP, it returns their public ip address which is linked to their registered domain name.
Is it possible to rename their internal domain name to .LOCAL right after I migrated their Domain Controllers to Window Server 2008 R2 ? Is that possible ????? Any ramification of renaming the internal .COM domain to .LOCAL????
Appreciate your feedback
