Confirm that the registry data and permissions are correct

The Windows Deployment Services PXE server must be able to read the necessary configuration settings from the registry. If any registry data is corrupt or missing, or if the PXE server does not have sufficient permissions, the PXE server will fail.

To resolve this issue, ensure that the registry data and permissions are correct.

Caution: Incorrectly editing the registry might severely damage your system. Before making changes to the registry, you should back up any valued data.

To perform this procedure, you must either be a member of the local Administrators group or have been delegated the appropriate authority.

To ensure that the registry data and permissions are correct: 

  1. Open Registry Editor. (Click Start, type regedit in the Start Search box, and then press ENTER.)
  2. Ensure that the WDSPXE registry key exists at the following location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WDSServer\Providers.
  3. If this key exists at the specified location, ensure that the SYSTEM account used by WDSPXE has permission to read from the registry. To do this, right-click the WDSServer node, click Permissions, click SYSTEM, and then ensure that Full Control is selected.
  4. If the WDSPXE key is missing or corrupt, you will need to reinitialize the server. To do this, open the Command Prompt window, run wdsutil /uninitialize-server, and then run wdsutil /initialize-server /reminst:<path to RemoteInstall folder>.


To verify that the PXE server has updated the configuration settings:

  1. Open Event Viewer. (Click Start, type Event Viewer in the Start Search box, and then press ENTER.)
  2. In the left pane, expand Custom Views, expand Server Roles, and then click Windows Deployment Services.
  3. Click the Date and Time column heading to sort the events based on date and time.
  4. Check for WDSPXE event 514.
