4KerberosThe kerberos client received a KRB_AP_ERR_MODIFIED error from the server computerA$. The target name used was cifs/computerB.mydomain.local. 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 (MYDOMAIN.LOCAL), and the client realm. Please contact your system administrator.
This message is logged when two computer accounts have the same IP address registered with a DNS server. E.g., both computerA and computerB have the IP address 10.10.10.233 registered with the DNS server.
This message is much more likely to be logged in networks that utilize DHCP, and may affect laptop computers more commonly than desktops.
The message can probably be ignored in most cases, unless the computers referenced are servers or computers that do not have a dynamic IP address.
To resolve the problem, first ensure that static IP addresses (if applicable) don't conflict. Then, run "ipconfig /registerdns" on the computers referenced (computerA and computerB) and "ipconfig /flushdns" on the computer where the message was logged.
