KDC Error

[Majid Almassari]

I am receving a KDC Error in Win2K Server event log (DC). Searching
Microsoft Knowledge Based did not reveal anything. KDC gives the client a
logon session key and a TGT. Here is the detailed information about the
event:

----------------------------------------------------------------------------

Any idea is to why SAM is failing KDC in an unexpected way?
