Kerberos Authentication ticket

[Nikos2019]

Hello everone

I have a server 2012 R2 and I get the following error:

A Kerberos authentication ticket (TGT) was requested.
Account Information:
Account Name: S-1-5-21-262885580-2243684832-3334250267-1001
Supplied Realm Name: DomainName.LOCAL
User ID: NULL SID
Service Information:
Service Name: krbtgt/DomainName.LOCAL
Service ID: NULL SID
Network Information:
Client Address: ::1
Client Port: 0
Additional Information:
Ticket Options: 0x40810010
Result Code: 0x6
Ticket Encryption Type: 0xFFFFFFFF
Pre-Authentication Type: -
Certificate Information:
Certificate Issuer Name:
Certificate Serial Number:
Certificate Thumbprint:
Certificate information is only provided if a certificate was used for pre-authentication.

Pre-authentication types, ticket options, encryption types and result codes are defined in RFC

I get 3304 ticket requests from this SID. But the problem is that I try to find this SID = user and it does not exist.


Anyone can give me any directions?

Thank you
