I mangage a Primary Domain Controller (Samba+LDAP) with 60PC. But 3-4 PC can't login to domain with error:

The trust relationship between this workstation and the primary domain failed.

56-57 PC login to domain normally.

LDAP and Samba service alway run on Server. And MyComputer\Manage on Client is normal:

If I power on PC and wait 1-2 minutes or try several login. I can login nomally.

Please help me fix this error.

This is typically due to one of two things:

  • Trust relationship is stale between PC and domain controller

In this case, you should unjoin and rejoin domain.

  • Time is out of sync between PC and domain controller

If time difference is more than 5 minutes apart by default, authentication will fail. Fix by getting the time to the actual time on each such that they match.

Hope that helps.
