4.3 Upgrading Existing Domain Controllers
If
the decision has been made to upgrade all or some existing hardware in
a Windows Server 2003 domain controller, the process for accomplishing
this is straightforward. However, as with the standalone server, you
need to ensure that the hardware and any additional software components
are compatible with Windows Server 2003. After establishing this, the
actual migration can occur.
4.4 Replacing Existing Domain Controllers
If
you need to migrate specific domain controller functionality to the new
Active Directory environment but plan to use new hardware, you need to
bring new domain controllers into the environment before retiring the
old servers. The process for installing a new server is similar to the
process with Windows 2000 Server. The DCPromo utility is used to promote a server to domain controller status.
Windows
Server 2003 supports an enhanced Configure Your Server Wizard, however,
which allows an administrator to designate a server into multiple
roles. This is the most thorough approach, and the following steps show
how to accomplish this to establish a new domain controller in a
Windows 2000 Active Directory domain:
1. | Open the Configure Your Server Wizard (Start, All Programs, Administrative Tools, Configure Your Server Wizard).
|
2. | Click Next at the welcome screen.
|
3. | Verify the preliminary steps, and click Next.
|
4. | Select Domain Controller from the list, and click Next.
|
5. | Check the settings at the Summary page, and click Next.
|
6. | After the AD Installation Wizard is invoked, click Next to continue.
|
7. | At
the Operating System Compatibility window, click Next to verify that
old versions of Microsoft software such as Windows 95 will not be
supported.
|
8. | Select Additional Domain Controller for an Existing Domain, and click Next.
|
9. | Type the password of an Administrator account in the AD domain, and click Next to continue.
|
10. | Type the domain name into the dialog box of the target AD domain, and click Next to continue. |
11. | Enter
a location for the AD database and logs. (You can achieve the best
performance if they are stored on separate volumes.) Click Next to
continue.
|
12. | Enter a location for the SYSVOL folder. Click Next to continue.
|
13. | Enter
a password for Directory Services Restore mode, which can be used in
the event of directory recovery. Click Next to continue.
|
14. | Verify
the tasks indicated, and click Next to continue. The server then
contacts another domain controller in the domain and replicates domain
information, as indicated in Figure 4.
|
15. | Click Finish when the process is complete.
|
16. | Click Restart Now when prompted to reboot the domain controller and establish it in its new role in AD.
