Resolution

This issue can be resolved via the UI or using regedit.
 

Editing via the UI

Change the Computer Name Properties on the web tier host computer.

  1. In the GUI install, go to System Properties > Computer Name > Change > More.
  2. Add the <domain> name (i.e., mydomain.com) to the primary DNS suffix of this computer.
  3. Click OK and restart the computer


Editing with regedit

The primary DNS suffix is stored in the registry at HKLM\SYSTEM\CurrentControlSet001\Services\Tcpip\Parameters

Note: Your CurrentContralSet<seq> value may be different.

  1. Navigate to HKLM\SYSTEM\CurrentControlSet001\Services\Tcpip\Parameters.
  2. Change the values for the following registry keys:
    • Domain (REG_SZ)
    • SearchList (REG_SZ)
