I currently have an Active directory domain (not SBS) and wish to move to SBS2011. Can SBS2011 coexist with an existing AD. My reason for implementing SBS is the integrated Email, OWA, and other bells and whistles in the SBS server.
Recently had a hard crash of an SBS2008 environment and lost my instance of SBS2008 and migrated to a Windows AD and sent Email to a 3rd party. Turns out due to the volume of email we need to retain, it is better to self host email and other applications on the local server which is why we are again considering SBS (2011).
Any thoughts on the planned migration and certainly your views on how we can use the current AD environment with SBS2011.
