Problems are solved after last Windows update. Please close this topic.

I also asked ChatGPT but I want to know why I have to edit value DependOnService. In other environment two DC's work properly without changed this value but both work on WS2019. DNS is set correctly. I don't have an idea...

Can someone help?

Hello, in our company there are two DCs. Main is WS2019 with FSMO role and second that we have configured last month is WS2025 as a backup AD. There have been problems with it from the start, primarily a replication error that occurs immediately after restarting the server. Sometimes it is enough to wait about 30 minutes and the replication starts working correctly on its own, and sometimes it does not start at all. I'm talking about command repadmin /replsummary and error (1908) Could not find the domain controller for this domain. DNS is set correctly, the primary is as backup one and second as localhost on the both servers. Additionally, after each server restart, an error related to DHCP appears in Event Viewer: 1059 The DHCP service failed to see a directory server for authorization. Even though DHCP works on both servers, as I can see from the scope. When I have added the value NTDS in registry value DependOnService in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCPServer, the error doesn't appear after reboot. Does anyone have any ideas? I will be grateful for any tips.
