SUMMARY
A backup domain controller (BDC) or standalone server can be added to the Small Business Server (SBS) domain. Because there can only be one computer running SBS on the network, any other servers added must run Windows NT Server.



MORE INFORMATION
The applications from the SBS server cannot be installed on the Windows NT Server computer.

If the SBS server goes down for any reason, the BDC will only be able to validate users logging on to the domain. Because the SBS applications cannot be installed on the BDC or standalone server, they will not be accessible should the primary domain controller (PDC) ever not be available.
