Netlogon 5722 - errors on Domain Controller

Hi there,

We have two Domain Controllers - DC1 and DC2.

In theory, everything works well. We didn't see any problems with user/app authorization, AD replication, ldap, dns, etc.

However, every 4 hours in System eventlog we can find new entry about NETLOGON id: 5722

The session setup from the computer DC2 failed to authenticate. The name(s) of the account(s) referenced in the security database DC2$. The folowing error occured: Access id denied.

We've executed set of DC diag commands, but there is no significant erros.

For example:
nltest /sc_query:mydomain.tld

It works on every workstation but it returns error on Domain Controllers..

I_NetLogonControl failed: Status = 1355 0x54b ERROR_NO_SUCH_DOMAIN

I'm confused.. I'm doing something wrong?

Best Regards,
Adam Erot
