Trust relationship between this workstation and primary domain failed

Problem Statement :
We are in the process of deploying Windows 7 and started getting this error: “Trust relationship between this workstation and primary domain failed”.  FYI – We started getting this error after our server team started deploying Server 2008 R2 Domain Controllers.  Rebooting seems to fix the problem, but we need a permanent preventative solution!


  • Make sure that the workstations are pointing to local DNS server IP as preferred DNS in NIC.
  • Also make sure that you “Enable NETBios over TCP/IP” under WINS tab at both places (Server, Workstation).
  • Dis-join the workstation from domain, delete computer account from ADUC and rejoin problem workstation again to the domain.

NOTE : If you are on Windows 2008R2 and Windows 7 platform,  Install this hot-fix .
