Fix broken trust relationship without rejoining domain

To fix the seemingly-random "The trust relationship between this workstation and the primary domain failed" error, you can remove the PC from the domain, then re-add it. Sometimes doing this is a PITA.

You can often fix the error using netdom.exe with the below steps. You can do it through your remote access utility, or by logging in as a local administrator.

  1. Extract netdom.exe and netdom.exe.mui from the Remote Server Administration tools. Or grab them from a machine that already has the tools installed.
  2. Put netdom.exe in C:\Windows\System32\ , and netdom.exe.mui in C:\Windows\System32\en-US\ , on the broken PC.
  3. Run the following command on the broken PC:

    netdom.exe resetpwd /s:myserver /ud:MYDOMAIN\adminuser /pd:(adminpassword)

    (Where "myserver" is your domain controller, "MYDOMAIN\adminuser" is a domain administrator, and "adminpassword" is the domain administrator's password.)

Enable file and print sharing from the command line

Run this command on the remote computer to enable file and print sharing (all one line):
