This paper provides information about the new Windows Server 2008 Header-Data Split feature and discusses the requirements for Windows drivers in the networking stack to be able to co-exist with this feature.

Also described are guidelines for driver developers who develop NDIS Intermediate (IM) drivers, NDIS filter drivers, NDIS Protocol drivers, Windows Filtering Platform (WFP) callouts, and TDI filter drivers to implement their drivers while remembering the Header-Data Split feature and to test their code for compatibility with this feature by using the tools that Microsoft provides.

This information applies to drivers that intend to run in the networking stack of Windows Server.

Included in this white paper:

•	Header-Data Split Compatibility
•	Instructions on How to Obtain and Use the NDISTest Tool Kit
•	Verifying Compatibility of NDIS IM, NDIS Filter, and NDIS Protocol Drivers
•	Verifying Compatibility of TDI Filters, WFP Callout Modules, and NDIS Protocol Drivers
