I have a customer that needs to run accounting software on a non-domain controller server. They will purchase another server but I would like them to purchase SBS 2008 for the Exchange and RWW benefits. I'd demote the current Server 2003 Standard and load the accounting software on it and migrate the user profiles to the new SBS 2008 Server. I understand that SBS will not allow other servers to be joined to the domain - in this case it appears to not matter.
How will the Server 2003 Standard interact with the SBS Server?
Will both servers need their own CAL's?
If the Server 2003 Standards non-domain controller is named the same as the SBS 2008 Domain will it be seamless to the users?
Is this the right approach to take?
