Cobbled this together some time ago; it uses WMI and generates a detailed output; you can optionally ...
* use -FailFast to ping machines before trying to query them,
* pass a Credentials object,
* pass a file to directly export the results to
If no export file is given, the results will end up in the pipeline and can be processed further as usual.
Pipeline input is supported, so you can do something like
Get-ADComputer -Filter "Name -like 'foo*'" | .\Get-PageFileLocationByWmi.ps1 -FailFast | Format-Table -AutoSize
