event 4 kerberos after install sp2

Hi,

Last week we installed Server 2003 SP2 in our netwerk. Our network consists
of 2 clusters (file and exchange). After the installation of sp2 we receive
the following error in the eventlog on several servers. (enterprise
machines)

The kerberos client received a KRB_AP_ERR_MODIFIED error from the server
host/filesrv01.domain.com. The target name used was APPLRAD01. 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 (DOMAIN.COM), and
the client realm. Please contact your system administrator.

In a forum I read that this would be a Bug. Anyone seen this before? Or
maybe someone has additional info.

Thx.
