powershell query

We have been running the following powershell query that should be listing all devices that have logged into the domain in the past 14 days (for some reason it seems to report on a larger result set than just 14 days).

import-module activedirectory
$Date = Get-Date
Get-ADComputer -Filter * -Properties Name, OperatingSystem, LastLogonDate | ? { $_.LastLogonDate -lt $Date.AddDays(-14) } |
Select Name, OperatingSystem, LastLogonDate |
Export-csv "c:\Report.csv" –nti

it returns about 400 devices in the report, but we know for a fact the numbers are larger than that. can anyone see any issues in the code that may mean it isn't producing a full report? It was run under the context of a domain admin account so shouldnt be a permissions based issue. also, should this code "work" to limit the devices to only those with a lastlogon within the last 14 days?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Try modifying it like so:
import-module activedirectory
$Date = Get-Date
Get-ADComputer -ResultSize Unlimited -Filter * -Properties Name, OperatingSystem, LastLogonDate | ? { $_.LastLogonDate -lt $Date.AddDays(-14) } |
Select Name, OperatingSystem, LastLogonDate |
Export-csv "c:\Report.csv" –nti

Basically you export everything and then filter out the ones fitting your search query.
By default, all queries are limited to 1000 entries unless otherwise specified.
Hope that helps.
