  1. Domains for Dummies Glynn Brooks NTPCUG Certification SIG November 18, 2006

  2. Today’s Topics • What are the most common models for computer networks? • What are the advantages of a Windows Server domain? • What must you know to develop software that runs in a domain environment? RGB Technical Solutions

  3. Windows Network Model History • Windows Workgroup • Windows 3.11 – “Windows for Workgroups” (1993) • Windows Domain Operating Systems • Windows NT Server 3.1 (1993) • Windows NT Workstation 3.5 (1994) • Windows NT Server 4 (1996) • Windows 2000 Server (1999) • Windows 2000 Professional (2000) • Windows XP Professional (2001) • Windows Server 2003 RGB Technical Solutions

  4. Workgroup Model – Small Office/Home Office (SOHO) • Workgroup computers are networked, but there is no formal membership or authentication process • A workgroup is peer-to-peer networking model – no one is in charge • Workgroups are difficult to manage beyond a dozen workstations RGB Technical Solutions

  5. Domain Model – SMB/Enterprise Windows Server domain:a group of computers running versions of the Microsoft Windows operating system that share a central directory database Active Directory:the central database that contains the user accounts and security information for the resources in a Windows Server domain RGB Technical Solutions

  6. Server Roles • In a domain, the active directory resides on computers that are configured as "domain controllers". • A domain controller is a server that manages all security-related aspects of a user and domain interactions, centralizing security and administration. RGB Technical Solutions

  7. Domain Controller Coordination RGB Technical Solutions

  8. Server Roles • File and print server • Web server and Web application services • Mail server • Terminal server • Remote access and virtual private network server • Directory services, Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP) server, and Windows Internet Naming Service (WINS) • Security Manager, Group Policy Management • Time Server RGB Technical Solutions

  9. Benefits of a Windows Server Domain • Centralized Administration - Management of the entire domain can be done with access to one database • Single Logon Process - Access to network resources can be granted through a single logon • Scalability - Very large networks can be created RGB Technical Solutions

  10. Summary and Recommendations • Applications that run in a domain environment have to honor the security model that has been established by the domain administrators • This normally means that you have to write code that strictly follows the “Trusted Subsystem Model” as described in the ASP .NET guidelines • Development and testing are best done in a domain environment – too many surprises occur when app is ported RGB Technical Solutions
