Locating obsolete users and computers

Just got easier (and faster!) in AD cmdlets 1.4! Before this release you still could manually filter user or computer records by pwdLastSet or LastLogonTimestamp – now user and computer retrieval by a bunch of attributes with an easy command like:

Get-QADUser -Inactive

or

Get-QADComputer -Inactive

This -Inactive parameter retrieves all accounts which have been in expired state, not used for logon, or with with password not being changed beyond the thresholds set by the  Set-QADInactiveAccountsPolicy cmdlet. Like this:

Set-QADInactiveAccountsPolicy -AccountExpiredPeriod 0 -AccountNotLoggedOnPeriod 30 -PasswordNotChangedPeriod 120

You can get the current settings in your environment by executing Get-QADInactiveAccountsPolicy.

In addition to -Inactive, there are other related parameters, such as -InactiveFor – which lets you specify the number of days the account has been in the inactive state:

Get-QADComputer -InactiveFor 30

Or you can go more granular and just use:

NotLoggedOnFor – to specify the number of days since last time the account was used to log on (note that LastLogonTimestamp parameter is used, which means that it is replicated between DCs and the retrieval is fast and works with any domain controller, but it requires 2003 or later AD schema and is only replicated every 9-14 days (so please don’t specify values less than 14):

Get-QADUser -NotLoggedOnFor 60

Get-QADComputer -NotLoggedOnFor 60

PasswordNotChangedFor – days since the account last changed password (computer accounts also have passwords which they are automatically rolling over):

Get-QADUser -PasswordNotChangedFor 180

Get-QADComputer -PasswordNotChangedFor 90

ExpiredFor – just for Get-QADUser – the number of days since the account expired:

Get-QADUser -ExpiredFor 30

You can also use a combination of Inactive/InactiveFor and ExpiredFor/NotLoggedOnFor/PasswordNotChangedFor – in which case the more specific parameters override the default inactivity criteria you set.
