Encryption Question

I don't know what you mean by offline. I do not have any servers (file or web).

Have a look at this:

http://cc.jlab.org/docs/services/windows/offline.html

The idea is that you access the files from your laptop (while connected
to the network), and mark them as 'available offline'. Windows then
copies them to an internal cache on the laptop, but makes it look as
though they are still available at their connected location (e.g.,
\\desktop_machine\share\folder\) even when you're not connected.

The actual locations of the cached files on the laptop are sort of
obfuscated (they get nonsense names & are stored under %windir%\csc, if
I recall correctly), but if you're using XP, you can also encrypt them.
See:

http://www.microsoft.com/technet/prodtechnol/winxppro/maintain/encrypt...line.ms

for details.

Hi Stu,
I have the same problem. However, min problem came after I pulled a registry
switch that turns off EFS on my Win Server 2003.
If I just copy one file with the xcopy /g switch, no problem. But copying an
entire C:\data to a network drive is not possible. I get the error:
"File creation error - The specified file could not be encrypted"

Anyway, just wanted to let you know that you're not alone with this problem.
I would be tremendously grateful if you could let me know if you find a
solution for this problem. I can be reached at fairlane76 DeleteThis @yahoo.com

My best guess would be you are trying to copy a file
with the system attribute set. According to M$, EFS
will not encrypt files with the system bit set (to prevent
you from encrypting files that are needed at startup before
the decryption is available .. see foot, shoot same )

Hi Mike,
Thanks for trying, but there are no system files involved.
The files and folder only have the A and E attribute set.
I have tried with both robocopy and xcopy, and none of them can do it,
although xcopy should be able to do it with the /g switch on. Anyway, here's
what happens:

C:\>robocopy c:\test v:\test\ /E /B

This produces this error message:

I orginally thought my command-line should look like this:
robocopy c:\test v:\test\ /E /PURGE /M
But that doesn't work either.

For xcopy this is what happens:

C:\>xcopy c:\test v:\test\ /m /d /e /r /c /q /g /h /y
File creation error - The specified file could not be encrypted.

Unable to create directory - V:\test

Hmmm - I sort of remember reading something recently about
a problem creating the top level directory involving EFS (but have
no idea where that was). You might try creating the top level
then going down one level on each side and see if that works.
Other than that , I don't have the answer.
