I am getting an error msg in the system log "The kerberos client received a
KRB_AP_ERR_MODIFIED error from the server host/sihfmx.sihf.org. The target
name used was SIHFEXCH01. 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 (SIHF.ORG), and the client realm." I can not recall making any
changes. Any ideas on how to approach this/fix it?

You will need to find the duplicate SPN and delete it. Here is an
article that goes over identifying the duplicate spn using ldp.
