Tech Tip: Rename system folders/Delegate subdomains in DNS

Windows 2000 Professional: Rename system folders

Several folders in the Windows 2000 file system have special names, such as My Documents, Recycle Bin, Search Results, My Computer, and My Network Places. You can rename some of these folders (i.e., My Computer, My Documents, and My Network Places) within the Windows interface. Other folders, however, require a different approach.

You can rename special Windows folders by modifying the registry. This approach can be useful when you want to apply a change to multiple users. It also enables you to use variables such as %username% or %computername% in the folder name and expand that variable to display the user or computer name.

To rename special folders, open the Registry Editor and locate the folder's key in the HKEY_CLASSES_ROOT\CLSID key, which you can find in the list below. Change either the Default value or the LocalizedString value, as indicated in the list.

If you want to use a replaceable variable, you must create a new LocalizedString value as a REG_EXPAND_SZ. Copy the existing value, delete LocalizedString, create a new one as a REG_EXPAND_SZ, paste the original into the value, and modify the folder name. You must use Regedt32.exe to create a REG_EXPAND_SZ value in Windows 2000.

Note: Editing the registry is risky. Before making any changes, back up the registry so you can restore it if something goes wrong.

Windows 2000 Server: Delegate subdomains in DNS

In DNS, a subdomain is a portion of a domain that's delegated to another DNS zone. For example, if TechRepublic hosted a support domain, that domain might be support.techrepublic.com. Likewise, a company might use subdomains for its various divisions, such as east.company.tld, west.company.tld, and so on.

To delegate a subdomain, you must create the delegation on the server hosting the parent domain. For example, to delegate support.techrepublic.com, the server hosting the techrepublic.com zone must include a delegation for the support subdomain.

Windows 2000 Server makes it easy to delegate a subdomain, thanks to the New Delegation Wizard. Follow these steps to delegate a subdomain:

  1. Open the DNS console, right-click the host domain, and choose New Delegation to start the New Delegation Wizard.
  2. Click Next, specify the subdomain name (such as support), and click Next.
  3. Click Add, add the host name of the server that will host the subdomain, click Resolve, and click OK.
  4. As needed, set up secondary servers to act as backups for the server acting as the primary for the delegated domain.
  5. Click Next, and click Finish to create the delegation.

At this point, the subdomain is delegated, but there are no records in its target zone. On the first server that will host records for the subdomain, create a new zone (such as support.techrepublic.com), and create the necessary DNS records for the zone. Repeat the process on other servers, or configure another server as a secondary for the zone.
