I was always thought to use internal domain name (company.local or company.corp) for Active Directory instead of (company.com or company.pl). Recently we were thinking that by using external domain name we can get some advantages for stuff like certificates for Exchange, Sharepoint and alike where internal and external name would be exactly the same making it unnecessary to buy special certificates.

What are advantages and disadvantages for both? What could be potential problem when doing so and what could be a big advantage?
