This Indicates That The Target Server Failed To Decrypt The Ticket Provided By The Client
to vote HI hope you can help, We have a site office with a AD server (2008
Event Id 4 Security-kerberos Krb_ap_err_modified
server) that unfortunately had to be switched off for about 6 weeks. We have just powered the server back on and we are getting Error (event id 4)
The Kerberos Client Received A Krb_ap_err_modified Error From The Server Domain Controller
"The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server server1$. The target name used was cifs/server1.domain.local This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal name (SPN) is registered on an account other than the account the target service is using. resetting the secure channel pw of a broken domain controller Please ensure that the target SPN is registered on, and only registered on, the account used by the server. Active directory is not replicating with this server. The server is an Active directory server, bridgehead server, Global catalogue, DNS and DHCP. I have gone through active directory and DNS and cannot see any duplicate entries for the server. Also if I try and browse one of the other servers (server2 – server 1)file share i get an error . Logon Failure: The target account name is incorrect But it works fine the other way (server 1 – server 2) I assume something is out of sync with it being switched off for 6 weeks.
