The kerberos subsystem encountered a PAC verification failure

[Guest]

In the local event log I am receing the following error Event ID 7 "The
kerberos subsystem encountered a PAC verification failure". I found article
88326 regarding
this issue and ran the steps that they recommend. All services are fine
with the exception of KDCSVC. When I enter the command Sc query KDCSVC I
reveive the following message:

OpenService Failed 1060:
The specified service does not exsist as an installed service

I could not find any information on how to resolve this issue. What
problems does
this creat and how do I go about resolving it?

Hi.



Is the machine on which you are running the sc.exe tool a domain controller?
If not, the KDC service will not be installed, and you don't have to worry
about it.



Other things to check..



a.. UDP port 138 is open between the client and DC


a.. Use the Netdom utility to reset the secure channel of each affected
machine. How To Use Netdom.exe to Reset Machine Account Passwords of a

If all else fails, turn up Kerberos logging as per..

PS - if you are running on a W2K3 server - the service is KDC not KDCSVC.

Thanks, Les
