We use MFE on the nokia mobiles to sync our emails on the moves. Recently for reasons unknown they all stopped working. We can get onto webmail but our mobiles we receive the following error according to the admin_log1.txt
HTTP error code=500

Tell me more about this issue and how to resolve it
Exchange ActiveSync returned an HTTP 500 response.
I cant see any problems on the server APART from the following error Event ID: 4
The kerberos client received a KRB_AP_ERR_MODIFIED error from the server host/sgbcoloisa2.christieg
roup.com. The target name used was ldap/sgbcoloisa1.christieg
roup.com. This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server. Commonly, this is due to identically named machine accounts in the target realm (CHRISTIEGROUP.COM), and the client realm. Please contact your system administrator.
Im not sure if this is causeing the problem, if so how can I resolve it?
Thanks for any help given.
