Kerberos EventID 4

One machine hangs constantly. We have checked hardware, disk space, RAM etc. I would like to rule out a particular possible issue. What I am asking for is to understand HOW to troubleshoot this issue, what the machine references are actually saying (names changed). This error is logged every hour and wondering if this could be causing hang (authentication) ? All DCs are Windows 2008.

The kerberos client received a KRB_AP_ERR_MODIFIED error from the server <machine_name>$.  The target name used was <server_name>/<machine_name>.<domain_name>. 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_name>), and the client realm.   Please contact your system administrator.
Thanks to all in advance for help.

Could you check in your DNS console in reverse lookup zone if there is a PTR record for DNS server, please?
Then reboot client PC.

Hi There

Both DCs are DNS servers and they do indeed have PTR records in the correct zone (verifiable via NSLOOKUP as well). The machine which hangs is Windows 2003 SP2 server and has just been rebooted but still logs the error. This may well NOT be the cause of the hang. This exercise is to rule this out.

Thanks for swift response.
