I used to share a USB key between my home PC (Win 2003 Server) and my
work PC (Win XP, joined to a domain).
To protect my data, I encrypt them via the EFS that is implemented into
the NTFS filesystem.
To do this I have exported the EFS certificate from my work PC to my
home PC and until some days ago all worked fine.
So I had my home PC able to open the encrypted files that I created at
work on the USB key.
But the company upgraded XP to Seven, and now I have no longer access to
any encrypted file from my home PC.
I have checked and it seems that Seven has generated another EFS
certificate, so I exported it (including the private key) and imported
it to 2003 (my home PC).
But,... still I do not have access to any file.
I do have exported the private key related to this certificate but,...
Win 2003 continues to deny the access to the encrypted files.
Does anyone know what I have to check to enlighten this problem?
BTW: if I import this new certificate to a *new* installation of Windows
(I have done this experiment via a virtual machine) all work flawlessly,
and I can open all the encrypted files.
Really, I believe I'm missing something... but what?
Thanks in advance.
