Question : Kerberos error in Exchange Cluster

Windows Server 2k3Sp2
Exchange 2k3Sp2 Clutered
njmail01=active node
NJMAIL=virtual cluster name

I am recieving a Kerberos error which doesn't seem to be affecting the server, but none the less I would rather not have it grow and cripple my network. Here is the event log

Event Type:      Error
Event Source:      Kerberos
Event Category:      None
Event ID:      4
Date:            4/18/2007
Time:            2:01:16 AM
User:            N/A
Computer:      njmail01
Description:
The kerberos client received a KRB_AP_ERR_MODIFIED error from the server host/njmail01.corpdomain.com.  The target name used was NJMAIL. 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 (CORPDOMAIN.COM), and the client realm.   Please contact your system administrator.

So my interpretation is nymail01 is sending a kerberos ticket to NJMAIL which is the same machine?
