Single-Label Domain DNS Resolution

Q. Clients on my network are trying to communicate with a single-label domain (i.e., a domain with just one component, as in savilltech instead of in another forest, but DNS resolution is failing. What's wrong?

A. By default, clients will use DNS to query single-label domain names only if a single-label domain exists in their local forest. To enable DNS for single-label domain names in either the local forest or remote, perform the following registry change on each client:

  1. Start the registry editor (regedit.exe).
  2. Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters registry subkey.
  3. From the Edit menu, select New, DWORD value.
  4. Enter a name of AllowSingleLabelDnsDomain and press Enter.
  5. Double-click the new value and set it to 1. Click OK.
