DOCUMENT:Q197859 15-MAR-1999 [winnt] TITLE :Server Roles in a Small Business Server Domain PRODUCT :Microsoft Windows NT PROD/VER:winnt:4.0,4.0a OPER/SYS: KEYWORDS:kbnetwork sbs ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft BackOffice Small Business Server versions 4.0, 4.0a ------------------------------------------------------------------------------- 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. REFERENCES ========== For more information, see the Start Here Guide that accompanies the installation software, Appendix B, Page 137.
