As usual Joe shared a great insight that trusts well-doing can in one way be verified by checking the trust accounts for their last password resets. When trusts are created the accounts for them are by default created under ‘Users’ container, and are named as TrustedDomain$ and just like computer accounts, trusts reset their password every 30 days, and . He showed how to look up the ‘pwdlastset’ attribute using his ADFIND tool. Below I show you the PowerShell way.

$old=(get-date).adddays(-30)

Get-QADUser -SearchRoot ‘mydomain.int/users’ -Name “*$*” -IncludedProperties pwdlastset | where {$_.pwdlastset –gt $old}

You may also sort and view the results as below

Any trusts that have not reset their passwords in last 30 days are probably no longer valid. If you are using ADWS on Windows Server 2008 R2, then something like below should suffice, assuming you have already created the $old variable using the same command as above.

Get-ADUser -Filter ‘Name -like “*$*”‘ -Properties pwdlastset | where {$_.pwdlastset –gt $old}
