Redirecting the computers container in Windows Server 2003 domains
http://support.microsoft.com/kb/324949
Normally the Computers ends up in the Computers Container, this is normally ok, but there are some things that you can’t do (like apply GPOsettings etc), after you moved your computers that you are not sure where they stand and if they get their settings correctly. After this you can apply settings to these computers as well, and new computers that are added will also have a possibility to run GPOs on.
Excerpt from the page:
3.
Create the organizational unit container where you want computers that are created with earlier-version APIs to reside (if the desired OU container does not already exist).
4.
Run Redircmp.exe from a command prompt by using the following syntax, where container-dn is the distinguished name of the organizational unit that will become the default location for newly-created computer objects that are created by down-level APIs:
redircmp container-dn container-dn
Redircmp.exe is installed in the %Systemroot%\System32 folder on new and upgraded Windows Server 2003-based computers. For example, to change the default location for a computer that is created with earlier-version APIs such as Net User to the OU=mycomputers container in the CORP.COM domain, use the following syntax:
redircmp ou=mycomputers,DC=company,dc=com
