Windows event id 4 (kerberos)

[raj esh L]

Hi,

Thanks for your response

I found many people faced these sort of problems on DCs and suggested to check SPN duplications. I verified those and could find any issues with it. But we are facing on member server which acts as print server. 

I verified this article and it is more related to IIS. However I checked DNS side and do not find any problem. If some one assist by analyzing through netmon captures that would be help full.

> The kerberos client received a KRB_AP_ERR_MODIFIED error from the server SLH-001155$.  The target name used was cifs/ATL017784.dir.ucb-group.com. 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 (DIR.UCB-GROUP.COM), and the client realm.   Please contact your system administrator.
