My company is in the process of rolling out Active Directory enterprise wide, with office 365 syncronization, Lync, Exchange, and Outlook.
We currently have no AD (yet); there are 400+ users in 5 separate offices.
The quandary we are facing is whether we should initially deploy Windows Server 2012, or 2008R2.
Certain elements are afraid of unknown issues with 2012, and one of our contractors suggested that we use 2008 because it has a larger knowledge base.
I've done all my testing in 2012, and I know that either one will work for our purposes. It's a fairly simple deployment (2 DCs and 1 ADFS server).
We will also be adding WDS, WSUS, Sharepoint, and WebHelpDesk.
Is there any valid technical reason that we should not go with the latest available version, assuming this is a complete description of the environment, or any caveat with Windows Server 2012 that we should be aware of?
