If a user-mode application has an open connection to the communication server port, any client port for that connection will remain open after FltCloseCommunicationPort returns. Thanks for trying Caleb, but that doesn’t help and there’s a lot of code involved in this question. A minifilter driver’s DriverEntry routine must perform the following steps, in order: Every minifilter driver must call FltRegisterFilter from its DriverEntry routine to add itself to the global list of registered minifilter drivers and to provide the filter manager with a list of callback routines and other information about the driver. The postoperation callback routine receives this pointer in its CompletionContext input parameter. However, a preoperation callback routine must never fail these operations.

It should be logging much more than just the create operations. Every minifilter driver must call FltRegisterFilter from its DriverEntry routine to add itself to the global list of registered minifilter drivers and to provide the filter manager with a list of callback routines and other information about the driver.
This is a kernel mode driver, though, so it’s natural for this not to work.
Information field to zero. Minifilter drivers are not required to register a FilterUnloadCallback routine.
The following list includes examples of global cleanup tasks that a minifilter driver might perform:. Every preoperation callback routine is defined as follows: The minifilter driver is responsible for performing any processing that is needed to undo the operation.
In fact the documentation for Minispy explicitly states that you need a user mode utility doesn’t state anything about a Windows service, though.
When setting the callback data structure’s IoStatus. To load this minifilter, run fltmc load minispy or net start minispy.

Preoperation callback routines are similar to the dispatch routines that are used in legacy file system filter drivers.
Post as a guest Name. Otherwise, the filter manager will ignore any changes to parameter values. So you have your driver running, great.
Register the minifilter driver by calling FltRegisterFilter. To install the minifilter, do the following:.
However, for an IRP-based operation, a minifilter driver’s preoperation callback routine can be called in the context of a system worker thread if a higher filter or minifilter driver pends the operation for processing by the worker thread.
We specialize in file system filter driver development. This callback routine is also referred minisph as the minifilter driver’s unload routine.
Status field of the callback data structure for the operation. You can also code your filter to attach automatically to certain volumes, and you could also do the filtering yourself by getting the file name with FltGetFileNameInformation and deciding minspy or not to log it. This is called when a request has been made to unload the filter. The filter manager passes this structure pointer in the CompletionContext input parameter to the postoperation callback routine.
