This will list computers and Last Logon Times from AD:
import-module ActiveDirectory
$dcs = Get-ADComputer -Filter { OperatingSystem -NotLike '*Server*' } `
-Properties OperatingSystem
foreach($dc in $dcs) { `
Get-ADComputer $dc.Name -Properties lastlogontimestamp | `
Select-Object @{n="Computer";e={$_.Name}}, @{Name="Lastlogon"; `
Expression={[DateTime]::FromFileTime($_.lastLogonTimestamp)}}
}

This doesn't seem to do anything...the PowerShell window simply sits there.

DeleteI'm not sure why that would be the case. The query isn't optimized, so if you had lots of objects in AD, it may take some time to populate them all. You can separate the two parts into single lines and use measure-command to time how long it takes to run them. You will need to import-module activedirectory first:
measure-command {$dcs = Get-ADComputer -Filter { OperatingSystem -NotLike '*Server*' } -Properties OperatingSystem}
measure-command {foreach($dc in $dcs) {Get-ADComputer $dc.Name -Properties lastlogontimestamp | Select-Object @{n="Computer";e={$_.Name}}, @{Name="Lastlogon"; Expression={[DateTime]::FromFileTime($_.lastLogonTimestamp)}}}}
