Hi
I have just connected a second domain controller, in dhcp options clients have priority set dns1 - current server, dns2 - new server. I don't know why, but some clients use name resolution through DC2? The first DC1 works all the time.

Something here could help.

This could be caused if the first DNS server is not able to response within 1 sec, then the client send the query to the second DNS server. After 15 minutes, the client reset the DNS priority list to the default settings...
This article explain the process
hth
I may have misspoken, users not only query the DC2 server but also log into it. There are logon events in event viewer. Why in this case they do not log on to DC1
Please run;
Dcdiag /v /c /d /e /s:%computername% >C:\dcdiag.log (run on PDC emulator)
repadmin /showrepl >C:\repl.txt (run on any domain controller)
ipconfig /all > C:\%computername%.txt (run on EVERY domain controller)
ipconfig /all > C:\problemworkstation.txt (run on problem pc)
Also check the domain controller System and Replication (DFS or FRS) event logs for errors since last boot. Post the Event Source and Event IDs of any found. (no evtx files)
then put unzipped text files up on OneDrive and share a link.

Just checking if there's any progress or updates?

Client computers will query the closest DC using DC Locator. If there is multiple DC's i the same site and all DC's have the same wright / priority, the clients may query any of them, the first DC to respond win.
If you really want that all clients authenticate on a specific DC, you could change the priority and the weight of the DNS records but personally, i would not change those values except in really specific cases...
