Event ID 263 — PXE Provider Support

  • Article

Applies To: Windows Server 2008

The Pre-Boot Execution Environment (PXE) server is used by Windows Deployment Services to provide network boot programs to client computers. The PXE server receives and responds to PXE requests, and the providers contain the business logic that determines how and when the requests are answered. The PXE provider included with Windows Deployment Services is named Binlsvc.dll.

Event Details

Product: Windows Operating System
ID: 263
Source: WDSPXE
Version: 6.0
Symbolic Name: E_WDSPXE_PROV_REQUIRED_CALLBACKS_NOT_REG
Message: Provider %1 was loaded from %2 and initialized successfully but the provider did not register the required callback functions. These callback functions are used to notify the provider when requests are received and to shutdown the provider. Windows Deployment Services server will unload the provider. However, since no callback has been registered the server may be unstable. Please correct the problem and restart the service.

Resolve

Examine the code of your custom provider or contact the vendor

Custom providers must meet the requirements defined in the Microsoft Windows Software Development Kit (SDK). To resolve this issue, examine the code of your provider to ensure that it meets these requirements, or contact the vendor for further support. To download the SDK, see https://go.microsoft.com/fwlink/?LinkId=104661.

Verify

To verify that the providers are working correctly:

  1. Open the Command Prompt window.
  2. At the command prompt, run wdsutil /get-server /show:config, and ensure that the expected providers are listed in the output.
  3. Open Event Viewer. (Click Start, type Event Viewer in the Start Search box, and then press ENTER).
  4. In the left pane, expand Custom Views, expand Server Roles, and then click Windows Deployment Services.
  5. Click the Date and Time column heading to sort the events based on time and date.
  6. Check for WDSPXE events 262 and 267, which verify that a provider was loaded (or unloaded) and initialized successfully.
  7. Ensure that you receive events 262 and 267 for each provider.
