We are running a Windows 2008 SBS Server and recently purchase a second server for a specific application. After speaking with a friend, he recommended upgrading the 2008 R2 server to a domain controller as a backup - its currently a member of the domain. I have a few questions that you might be able to help with:
1. We only have 5 lisences with the 2008 R2 and we have 40 SBS Lisences. If the SBS server went down (for whatever reason) and users validated their user accounts to the domain, how would this affect the lisences?
2. other than users being able to log on to the domain, what would the advantage be?
3. I've never ran DCPromo to upgrade a domain controller. I've read a few books/videos and looks straight forward, is there any potential issues i need to look into?
The SBS server has direct storage and holds all the exchange and shares.
Any help/suggestions is appreciated, thanks.
