About EFS and local certificate that I want to export

Hello,

I have test something but I am not sure that I am right !

I have two computers XP_A and XP_B member of an active directory domain with no certificate authority.
There are two users : Pascal and Isabelle.

1. Pascal logs on XP_A and encrypt a file with EFS.
2. Pascal exports his certificate through Internet explorer (with or without the private key, the issue will be the same)
3. Now, on XP_B, an admin install the Pascal certificate on the computer (in the "Trusted People" store).
4. Isabelle logs on XP_B and encrypts a file with EFS, then she adds the Pascal certificate to authorize him to access this encrypted file.
5. Pascal is connected to XP_A and opens the encrypted files for which his certificate is attached on XP_B,but he still has an access denied.

Question : Why Pascal is not able to access this file from the network ? (From XP_A to XP_B)

More generally, if I export an EFS user certificate from one computer to another, can I access the encrypted file through the network.

With a certificate authority, I think there will be no problem but I would like to understand why like this it is not working.

Thank you :)
