While processing a TGS request for the target server krbtgt/DOMAIN.LOCAL, the account DESKTOP04$@DOMAIN.LOCAL did not have a suitable key for generating a Kerberos ticket (the missing key has an ID of 8). The requested etypes were 18. The accounts available etypes were 23 -133 -128 3 1.
This event can occur if you have a mixed 2008+ and 2003 domain environment. It should be safe to ignore since the computer will usually fall back to an older supported etype.
