The kerberos client received a KRB_AP_ERR_MODIFIED error from the server %1. The target name used was %3.

Hi Experts,I see the below error in sql server log.The kerberos client received a KRB_AP_ERR_MODIFIED error from the server %1. The target name used was %3.Read couple of blocks and can able to find below1. This problem occurs because two or more computer accounts have the same service principal name (SPN) registered - duplicate SPNs. Event ID 11 is logged when the Key Distribution Center (KDC) receives a ticket request, and the related SPN exists more than one time when it is checked on the global catalog (GC) for forestwide verification.2. A Kerberos ticket is encrypted by using the client computer account's password for the resulting encryption used on the ticket. If the computer account's password changes during the authentication process, the ticket cannot be decrypted. This can happen if a computer account was moved to a different forest and the original computer account object was not deleted​Is this right, what i can suggest to the network/sysadmin team.Thanks in advanceSai
