1. Module 8: Implementing the Placement of Domain Controllers

2. Overview Implementing the Global Catalog in Active Directory Determining the Placement of Domain Controllers in Active Directory Planning the Placement of Domain Controllers

3. Lesson: Implementing the Global Catalog in Active Directory Review of a Global Catalog Server How to Enable a Global Catalog Server When to Customize a Global Catalog Server How to Customize a Global Catalog Server What Is Universal Group Membership Caching? Multimedia: The Role of Universal Groups in the Logon Process How to Enable Universal Group Membership Caching for a Site

4. Review of a Global Catalog Server Domain Global Catalog Server Global Catalog Result Query

5. How to Enable a Global Catalog Server Your instructor will demonstrate how to enable a global catalog server by using Active Directory Sites and Services

6. When to Customize a Global Catalog Server firstName lastName email address accountExpires distinguishedName firstName lastName email address accountExpires distinguishedName Common Attributes Global Catalog Server Create additional attributes Add only the additional attributes that you query or refer to frequently department firstName lastName email address accountExpires distinguishedName department firstName lastName email address accountExpires distinguishedName Changed Attributes

7. How to Customize a Global Catalog Server Your instructor will demonstrate how to customize a global catalog server by using Active Directory Schema

8. What Is Universal Group Membership Caching? At first logon, the local domain controller requests information from the global catalog server After the first logon, the local domain controller uses the cached copy of the universal group membership Small Site Universal Groups Large Site User’s Cached Universal Group

9. Multimedia: The Role of Universal Groups in the Logon Process This presentation describes the logon process in three situations: With the global catalog available Without the global catalog available With universal group membership caching enabled

10. How to Enable Universal Group Membership Caching for a Site Your instructor will demonstrate how to enable universal group membership caching by using Active Directory Sites and Services

11. Practice: Implementing the Global Catalog in Active Directory In this practice, you will enable a global catalog server

12. Lesson: Determining the Placement of Domain Controllers in Active Directory What Is Active Directory Sizer? Parameters for Active Directory Sizer How to Use Active Directory Sizer

13. What Is Active Directory Sizer? CPU Requirement Network Requirement Hard Disk Requirement Active Directory Sizer Memory Requirement Number of Domain Controllers Global Catalog Database Size Domain Database Size Number of Global Catalog Servers Intersite Replication Bandwidth Active Directory Sizer provides estimates for:

14. Parameters for Active Directory Sizer  Users concurrently active during a peak hour  Number of groups that a user belongs to  Logon rate per second during a peak hour  CPU utilization limit  Administrative requirements  DNS requirements  Users concurrently active during a peak hour  Number of groups that a user belongs to  Logon rate per second during a peak hour  CPU utilization limit  Administrative requirements  DNS requirements Example Parameters Administrator Active Directory Sizer Output Report

15. How to Use Active Directory Sizer Your instructor will demonstrate how to: Use Active Directory Sizer Examine the output of Active Directory Sizer Use Active Directory Sizer Examine the output of Active Directory Sizer

16. Practice: Determining the Placement of Domain Controllers in Active Directory In this practice, you will determine the placement of domain controllers by using Active Directory Sizer

17. Lesson: Planning the Placement of Domain Controllers Guidelines for Placing Domain Controllers Guidelines for Placing Global Catalog Servers Guidelines for Enabling Universal Group Membership Caching Guidelines for Placing Active Directory Integrated DNS Servers

18. Guidelines for Placing Domain Controllers Place a domain controller based on: Number of users Site-aware applications Server resources Place a domain controller based on: Number of users Site-aware applications Server resources Do not place a domain controller that has: Inadequate physical security Poor computer maintenance Do not place a domain controller that has: Inadequate physical security Poor computer maintenance Determine the number of domain controllers based on: Number of users Performance characteristics Determine the number of domain controllers based on: Number of users Performance characteristics

19. Guidelines for Placing Global Catalog Servers Ensure that a global catalog server has enough disk space Ensure that a global catalog server can respond to queries immediately Provide enough WAN bandwidth Make all domain controllers global catalog servers Provide redundant global catalog servers

20. Guidelines for Enabling Universal Group Membership Caching Enable if sites meet specific conditions Consider alternatives first Do not enable if lost connectivity would affect network resources

21. Guidelines for Placing Active Directory Integrated DNS Servers Place at least one DNS server in every site Use an Active Directory integrated DNS that uses an application partition Use a local DNS if an Active Directory integrated DNS is in use Configure domain controllers with IP addresses for at least two DNS servers

22. Multimedia Practice: Placing Domain Controllers Universal Group Caching Global Catalog (GC) AD integrated DNS (DNS) Domain Controller (DC) In this practice, you will plan the placement of domain controllers DC DNS GC DC DNS Redmond DenverVancouver T1128Kbps
