Today I was checking an Event Viewer in one of my application the following Log has been recorded with Red Mark
Event Type: Error
Event Source: Kerberos
Event Category: None
Event ID: 5
Time: 4:57:54 PM
The kerberos client received a KRB_AP_ERR_TKT_NYV error from the server HESHJSJDT062D9S$. This indicates that the ticket used against that server is not yet valid (in relationship to that server time). Contact your system administrator to make sure the client and server times are in sync, and that the KDC in realm HINNSHJ.AE is in sync with the KDC in the client realm.
