So how can you fix this error? Unfortunately, the simplest fix isn't always the best option. The easy fix is to blow away the computer account within the Active Directory Users and Computers console and then rejoin the computer to the domain.

Doing so reestablishes the broken-trust relationship. This approach works really well for workstations, but it can do more harm than good if you try it on a member server. The reason for this has to do with the way that some applications use the Active Directory. Take Exchange Server, for example. Exchange Server stores messages in a mailbox database residing on a mailbox server.

However, this is the only significant data that is stored locally on Exchange Server. Microsoft support article on the topic: Recently, when I ran into this problem, the virtual machine that reset was an enterprise certificate authority joined to my test domain.
