Encrypt the data in the lan-redirector?

Hi,

I develop a file system filter driver(Modefied from the FileMon) to encrypt
the data sended to the network.So,i did the following:first,i attatched the
encryption filter to the lan-redirector;and then,i encrypted the data in the
write-dispatch of the device object attatched to the lan-redirector.But it
didn’t work!I found that the data was encrypted correctly,but after i
forwarded the irps to the next driver,the system would crash,and the remote
file was not encrypted at all,it seemed that the encrypted data could not be
writed to the remote SRV.Can anaybody give me some suggestions?

thanks
frank

Have you reviewed all the posts on encryption in here? And all the posts
about attaching to lanman?

If so, then can you give us the details that these posts end up requiring?

Read about the copyright restrictions on FileMon and comply with them by
licensing the code from WinInternals. The last released source for FileMon
had many issues and is not suitable for a commercial product.
