Based on my research, a Kerberos ticket is encrypted by using theclient computeraccount's password, if thecomputer account's password changes during the authentication process, the ticket cannot be decrypted, and the authentication Commonly, this is due to identically named machine accounts in the target realm (), and the client realm. x 8 Anonymous This event will occur if you present a service ticket to a principal (target computer) which cannot decrypt it. Write the text yourself, as a copy-paste can give problems (I suspect the Unicode-formatting to be different on some webpages). have a peek at this web-site

The machine returned the IP address for a different computer, with the destination rejecting the connection because the login account for that computer was incorrect. If not, why? I typically create a "dhcp-dns-update" user to do this - no special permissions have been necessary in my experience.

The Kerberos Client Received A Krb_ap_err_modified Error From The Server Cifs

I have tried to collect as many sources to the problem that I could find and a solution to each one starting with the one that most likely could cause the This will catch duplicates in the same forest. Ensure that the service on the server and the KDC are both configured to use the same password. This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server.

If this is you, follow these steps. My go-to settings are to enable DNS dynamic updates for devices that request it (if requested by the client) and to delete a record when the lease is deleted.

Resetting The Secure Channel Pw Of A Broken Domain Controller If the server name is not fully qualified, and the target domain ($domain$.COM.AU) is different from the client domain ($domain$.COM.AU), check if there are identically named server accounts in these two Possibly even a user account. As for deleting the cached credentials, this action will force the machine to synchronize the newest credentials with PDC when an authentication is needed.

All of the servers are Windows 2012 (not R2). The Target Name Used Was Cifs/ Verify if one of the machines no longer exists. See ME321044 to solve this problem.

See EV100437 (Symantec TECH207085).

You can use the following method to determine of there are any duplicate machine names registered in the same forest. Issues with the MTU SizeThe network packets that are send through the wires have a certain length. The target name used was MSOMSdkSvc/SCSMDW. Reset Secure Channel Password Domain Controller Attempt a net use then check the NetBIOS cache (nbstat -c) and the DNS cache (ipconfig /displaydns).

We did revisit the problem a few days after the fix, and it came down to user permissions. x 126 Anonymous The cause of this problem turned out to be two DCs sharing the same IP address, one of which was offline. We suspect it came into their network on one of the system administrator's computers which, combined with your theory, explains how and why it spread to the servers as fast as have a peek here Run the following command specifying the name of a GC as “GCName”.
