Restricted Computer or Trust Relationship Names

Internet$

NOTE: Windows 2000 appends a dollar sign ($) to the end of these names, which prevents using a computer name or trust relationship name of Internet.

To resolve this problem, follow these steps:

1. Move the computer that you want to restore to a separate network that is isolated from you production network.
2. Restore this computer from backup. Do not restart the computer when the restoration is complete.
3. On the temporary RID Master domain controller on the production network, open a command prompt, type repadmin /showvector, and then press ENTER.
4. Shut down the temporary RID Master domain controller, and then move it to the separate network with the restored computer.
5. Start both computers.
6. Use the Sites and Services Manager Snap-in to initiate replication between the two computers. To do so, follow these steps:
A. Click Start, point to Programs, point to Administrative Tools, and then click Active Directory Sites and Services.
B. Expand the Sites container in the left pane, and then expand the container that represents the name of the site containing the target server that you must synchronize with its replication partners.
C. Expand the Servers container, and then expand the target server to display the NTDS Settings object (an object that represents the settings for the domain controller).
D. Click the NTDS Settings object. The connection objects in the right pane represent the target server's direct replication partners.
E. Right-click a connection object in the right pane, and then click Replicate Now.

Windows 2000 initiates replication of any changes from the source server (the server represented by the connection object) to the target server for all the directory partitions that the target server is configured to replicate from the source server.

7. Transfer all the operations master roles back to the original role-holder.
8. Move both computers back to the production network.

Can we create 2 users with the same name in the Active Directory?

The sAMAccountName must be unique (among all objects, including users, computers, and groups) in the domain. In addition, the Relative Distinguished Name (the value of the cn attribute) must be unique in the parent OU or container.

Can I rename a computer object in Active Directory?

Rightclick on Start button or press the Start button on your keyboard and the X key simultaneously, and select System. Click on Rename this PC and enter new name for your device according to your naming policy.

What is Windows Server uninstall?

In the context of the Microsoft Windows NT line of computer operating systems, the relative identifier (RID) is a variable length number that is assigned to objects at creation and becomes part of the object's Security Identifier (SID) that uniquely identifies an account or group within a domain.
