I have this error in all DC's on my company:

Error DNS-Server-Service Event ID 4015

The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The extended error debug information (which may be empty) is "0000051B: AtrErr: DSID-030F2312, #1:
      0: 0000051B: DSID-030F2312, problem 1005 (CONSTRAINT_ATT_TYPE), data 0, Att 20119 (nTSecurityDescriptor)". The event data contains the error.

Could you help me, please?

Regards, David.

I feel the little information I have sent you :-). I have modified things in the dns and I have taken the log.

Can you take a look at the attached file and tell me from your expert point of view how is the health of AD and DNS in my company?

Suggestions and improvements will be welcome.

Greetings and thank you.
