I am installing AD on a Server 2008 R2 box. It is a clean install and is intended for a small business(10 users). The intention is to install exchange 2010 on the server.
My predicament is what to define the fqdn as. I have heard conflicting advice as to whether to use a 'real' domain or a .local. I have also heard that changing it later is troublesome. I am after some advice to guide me through this selection so I don't end up a cul-de-sac.
If there are any other pitfalls I shouldbe aware of please don't hold back :)
