Sometimes you\u2019ll find that for any one of a multitude of reasons, a workstation\u2019s computer account becomes locked or somehow otherwise disconnected from the actual workstation (say, if a machine with the same name joins the network, or if it\u2019s been offline for a very long time). When you try to log on to the domain you\u2019ll get a message that states:<\/p>\n
<\/p>\n
\u201cthe trust relationship between this workstation and the primary domain failed\u201d<\/p>\n
<\/p>\n
Now, what I would normally do in this situation is un-join and re-join the workstation to the domain, which works, but creates a new SID (Security Identifier) and can therefore break existing trusts in the domain with that machine, and of course it requires a reboot. So if you don\u2019t want to reboot, and you don\u2019t want to break existing trusts, do this:<\/p>\n
<\/p>\n
Use netdom.exe in a command prompt to reset the password for the machine account, from the machine with the trust problem.<\/p>\n
