Hi,
I am trying to copy a encrypted file on a server to a client machine share. On the client machine i want the file to remain encrypted. I use the following command to to a copy the encryprted file. This command is run by the user who has encrypted the file.

1. I connect to the clinet user specifying a account

NET USE \\ClientName\IPC$ /USER:userid pwd

2.Copy the encrypted file

COPY \\server\filename \\client\ShareName$\FileName

//This command must copy the file on the client machine using the context
//of the user account i specified while connecting to client.

3. Delete the connection

\\ClientName\IPC$ /d


The problem is the copy command fils to encrypt the file while copying over.
I get the following error : The specified file could not be encrypted.

The weird thing is it was working for so long before it hit this error.

When i saw the eventvwr i saw "efs" logging the following message:

EFS does not support encryption over network established using NTLM protocol.


I am not sure if i am missing anything.

Any help will be apperciated!

Thanks
