HI

One of our W2K3 server has been disconnected from the network for a while and we are now gettings the following error in the Event log  :
The kerberos client received a KRB_AP_ERR_MODIFIED error from the server host/atlan-red01.atlanrs.com.  The target name used was ldap/atlan-red01.AtlanRS.com/AtlanRS.com@AtlanRS.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 (ATLANRS.COM), and the client realm.   Please contact your system administrator.

could you direct me in the right direction ?

thanks

thanks,
I tried to use the ldifde command. I ran it on the PDC emulator and on the DC  have problem with. I get the same result. It makes me think it is DNS related,

I set the default DC to use the PDC emulator for DNS. and I still get the same problem.

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.
