I have SBS2008 with 60 users and the company needs to split into two separate geographical locations each with 30 users. The domain will be the same at both locations. Users currently use their files off a NAS. Emails are important and is handled by exchange server of SBS2008. The two sites will be connected by DSL (with dynamic IP).
How best can I join these two sites using SBS 2008 with all users sharing a common domain, their files and maintain a transparent transition? What additional hardware will be required?
This is a temporary measure for a period of a year when all users will be housed at larger premises. At this point migrating to Win Server 2012 will be an option with the purchase of new equipment. If equipment has to be purchased now during this split and reused later, this will be a bonus.
