secure channel (SC) reset on DC failed with error: no logon servers available

I'm struggling to resolve this error. I think I've correctly set up the DNS-part, by creating Secondary Zones for forward and reverse look-up. I can ping all servers, ports are open etc. At some point, I can validate the trust perfectly. But when I check again at a later point (now = next day), I'm getting this error (I had this before, first tried recreating everything).

The outgoing trust was successfully validated.

The secure channel (SC) reset on Active Directory Domain Controller \DC-02.mydomain2.local of domain mydomain2.local to domain intranet.mydomain1.local failed with error: There are currently no logon servers available to service the logon request.

Domain controllers:

The issue always mentions DC-02, not sure if this is relevant? What should I check?

I also tried resetting the password, as suggested. That leads to a "No Logon servers are available" error.

Update: when validating again from domain 1, it claims the RPC server is unavailable. Further investigation: it seems all of a sudden, from the PDC, I can't ping by the name of the domain or domain controllers of domain2. I double-checked this yesterday, then it worked. From other domain controllers in domain 1, it still works. I disabled Kaspersky Endpoint Security, then ran a ipconfig /flushdns and tried again: working. Could it be Kaspersky, or a DNS-issue (weird, since the same DNS-servers are used and on other DC's it's working?)

Please verify the following:

  1. In the Condintional forwarders in DNS setting - Add the other domain's DNS server name and IP.

  2. Open ncpa.cpl - Goto properties of IPv4 and then click on advanced. Goto DNS - clcick on the radio button - "Append these DNS suffixes (in order):" Then add the domain - e.g. lab.com in it.

Perform the above two steps in both the domain's Domain controllers/DNS servers.
