EFS remote with delegation won't stop using self-signed cert.

Hello All,

Windows 2003 file server(trusted for delegation), XP client, Windows 2003
Certificate Server

I have a peculiar and reproduceable issue using EFS over the network to a
file server.

When a user connects to the server from the network for the first time, a
profile is created and presumably the key pair is stored in the profile.
Ideally the user would have a roaming profile and their proper current key
pair would be available in the roaming profile. (This works fine on this
server as long as the user has a roaming profile)

My problem comes in when a user without a roaming profile connects over the
network and encrypts a file. The o/s creates the profile and issues a
self-signed certificate... Darn, got to make the user a roaming profile.
Delete the profile from the file server, make the user a roaming profile.
Remove the encrypted files.... Try to encrypt files again. same
self-signed certificate is used.

All of the documentation I have read says that the key pair is stored in the
profile. Is there some place that the key pair is cached for the system to
use when delegating? I have tried several variations, logging on to the
file server locally and importing proper key pair, but once the user has
encrypted with the self-signed certificate, I can't figure out how to make
it start using the CA issued cert.

Please Help!

Thanks in advance, reply to group,

Greg Wilcox
