Event ID 4771

Getting hundreds of errors below with event id 4771 on windows 2012 server.

Can anyone please help?

      Service Name:            krbtgt/domain.com

Network Information:
      Client Address:            ::ffff:192.168.0.xxx
      Client Port:            54214

Additional Information:
      Ticket Options:            0x40810010
      Failure Code:            0x25
      Pre-Authentication Type:      2

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 and failure codes are defined in RFC 4120.

If the ticket was malformed or damaged during transit and could not be decrypted, then many fields in this event might not be present.
