Installing and Managing Domains, Trees, and Forests
Lesson Summary
A trust relationship is a link between two domains in which the trusting domain honors the logon authentication of the trusted domain. In Windows Server 2003, trusts can be created manually or automatically, can be transitive or nontransitive, and can be one- or two-way. Windows Server 2003 supports the following types of trusts: tree-root, parentchild, shortcut, realm, external, and forest. You use the New Trust Wizard to create explicit trusts, which is accessed from the Active Directory Domains and Trusts administrative tool.
Troubleshooting Lab
To prepare for this lab, you must first remove the woodgrovebank.com Active Direc tory installation. You should also remove the DNS server service. The following steps guide you through this task.
Note The commands in this lab assume that your CD-ROM drive is D. If it is something else, use that letter in place of D in the steps below.
1. Manually or automatically remove the woodgrovebank.com Active Directory install. To remove it automatically, insert the Supplemental CD into the CD-ROM drive on Server2. Click Start, click Run, and then type: dcpromo /answer:D:\70-294\Labs\04\RemoveWoodgroveDC.txt, and then press Enter. 2. Log on to Server2 using the local administrator user name and password. 3. To remove the DNS server service, click Start, point to Control Panel, and click Add or Remove Programs. 4. On the Add Or Remove Programs window, click the Add/Remove Windows Com ponents icon. Wait for the Windows Components Wizard to load. 5. Clear the Networking Services checkbox and click Next. This will remove all Networking Services, including the DNS server service. 6. Click Finish to complete this process. Close the Add or Remove Programs window. 7. Now configure Server2 as a member server of contoso.com, as you learned to do in 2.

Once this is complete, you are ready to begin the troubleshooting lab. The troubleshooting scenario follows: You are a network administrator for Contoso Pharmaceuticals. Another member of your network administration team returns from a temporary assignment that lasted sev eral weeks. Her computer was offline the entire time she was away. She returns to the office and starts her computer. She has trouble logging on and then she finds an error in the Event Viewer console s System log. She asks you to look at the error. (To see this error, you must open a saved Event Log on your Supplemental CD-ROM.) 1. Log on to Server2 as the local administrator. Place your Supplemental CD-ROM into the CD-ROM drive of Server2 if you have not already done so. 2. Click Start, click Run, type eventvwr.msc, and then press Enter. 3. On the Event Viewer console, right click the Event Viewer (Local) icon, and then click Open Log File. The Open dialog box is displayed. 4. In the File Name list, type D:\70-294\Labs\04\3210.evt. In the Log Type box, click the down arrow and select System. Click Open. A Saved System Log appears in your Event Viewer. 5. In the right window pane, scroll to the only error event in the saved log and double-click it. The Event Properties dialog box opens. Review the error message and then click OK. Close the Event Viewer.
Note This type of error can occur if a member server is unable to synchronize its machine password with the domain controller. If you haven t done so already, install the Windows Support Tools on Server2. The Netdom commands in the following steps show you how to diag nose and repair this issue. Before you attempt any of the following commands, ensure that your domain controller has been on for at least 15 minutes.
6. At the command prompt, reset the secure channel by typing netdom reset server2 /domain:contoso. You should see a confirmation message that reads: The secure channel from SERVER2 to the domain CONTOSO.COM has been reset. You ve now solved the problem. 7. Now verify that the secure channel between the member server and domain controller is functioning properly. At the command prompt, type netdom verify server2 /domain:contoso.com. The following message appears: The secure channel from SERVER2 to the domain CONTOSO.COM has been verified. The connection is with the machine \\SERVER1.CONTOSO.COM , indicating the channel is functioning properly.
