hello,
in our domain controllers there are so many event 16 which indicates 'while processin a TGS request for the target server XXX the account YYY did not have a suitable ..... '
we do not have configured des to disable and i have no idea why is that generating so much.
have you guys experienc this?
the YYY acount i mentioned can be computer acc or user.
update:
take a look below. this error is strange!
While processing a TGS request for the target server krbtgt/CONTOSO.COM, the account J.Doe@ROOT.CONTOSO.COM did not have a suitable key for generating a Kerberos ticket (the missing key has an ID of 8). The requested etypes were 18 17. The accounts available etypes were 18 17 23 -133 -128 24 -135. Changing or resetting the password of CONTOSO.COM will generate a proper key.
there is a logic problem here. error says the requested type were 18,17, but also says the available types were 18,17,23,... . If 18,17 were available, then why this error generated?
Hi Mat,
Just wondering if you could give some more background like:
1.
Were there any changes recently in the domain, i.e. did you just install 2008 R2 domain controllers?
2.
Do you still have 2000/2003 DCs in the environment?
3.
Did you recently increase the DFL/FFL of the domain?
Thanks in advance and sorry to be asking dumb questions.
Glen
