Hi all,

I have another question re the EFS Recovery Agent.

I need to use EFS in a specific server that belongs to a Windows 2k
domain. This domain (which uses a PKI - users logon to their XP
stations using smart cards)has an EFS policy using the default domain
administrator (Administrator).

Unfortunately, when I tried as a test to encrypt a file the system
denies to do so. Upon investigating, I found out that the
Administrator certificate for EFS purposes has already expired.

My questions at this point are:

1- can I define a local EFS policy for that particular server, using
cipher.exe utility allowing me to bypass the domain policy ?

2- how should I proceed in order to renew the expired certificate in
order to "repair" the domain wide EFS policy ? In my opinion, I should
proceed as follows but I would like a confirmation from someone how is
more knowlegeable about this issue:

a- setup in AD a domain account to be designated as Recovery Agent (or
use an existing one)
b- logon to a workstation using this account
c- create recovery key pair using cypher /r
d- import the certificate into the account's personal store (should I
select the .cer file or the pfx file ?)
e- add the recovery agent in the domain EFS policy

Thank you very much for your time !
Bar
