SUMMARY
A new interface has been added to the Server Message Block (SMB) server which allows an acceleration driver to "hook up" to Srv.sys for acceleration of direct host IPX operations. Network Interface Cards that support this acceleration are available from third-party vendors.



MORE INFORMATION
The interface is a new FSCTL (FSCTL_SRV_IPX_SMART_CARD_START) which passes a data structure into Srv.sys (struct SRV_IPX_SMART_CARD) having pointers to the driver acceleration routines. When a direct host IPX client subsequently does open, close, and read operations on disk files, Srv.sys passes the request to the acceleration driver for servicing.

This new interface is included in Windows NT 4.0, and is available for Windows NT 3.51.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51. This problem has been corrected in the latest Microsoft Windows NT U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
