Hi, One of our server (windows 2003 server with sp1) having problem it keep on generating error in event log event id 4 AND EVENT 5719 The error is The kerberos client received a KRB_AP_ERR_MODIFIED error from the server host/abcd.abcd.co.in. The target name used was ldap/abcd.abcd.co.in. 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 (abcd.CO.IN), and the client realm. Please contact your system administrator. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/even... This computer was not able to set up a secure session with a domain controller in domain abcd due to the following: The RPC server is unavailable. This may lead to authentication problems.
