Can I name a extenal domain and intenal domain like so? {samename}.com for external email domain {samename}.local for internal actvie directory name? Are there any issues with this?

Can i use {samename}.local for AD domain if I am using {samename}.com for external email domain? External DNS is hosted outside of AD domain.

Yes you can... from a DNS perspective they are different domains. -- Mike Burr Technology

It is often the case that companies use their external domain (i.e. CONTOSO.com) for their internal Active Directory domain, and this is completely fine, except when you want to access your website which is hosted on an external server. Usually this happens when exchange server users wants to access there email over the web. http://www.virmansec.com/blogs/skhairuddin
