I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That above will get pagefiles, but not output to a CSV.  Here I've completed the script to give you that function.  Just change the top 2 lines with the location of the servers you want to check and the place where you want the CSV to go.  In the servers.txt file, on each line put in the name of the server you want to check.

$serverFile = "C:\test\servers.txt"
$outputFile = "C:\test\pagefiles.csv"

Retrieves  page file location information from  local or remote computers.


The script uses .Net RegistryKey class and its OpenRemoteBaseKey method to retrieve the information.

Each computer is contacted sequentially, not in parallel.


Run it from the location where the script is stored.

PS C:\Users\Administrator\Downloads> .\PageFileLocation.ps1

ServerName                                                  PageFileLocation

Here's a version that uses WMI and generates a more detailed output; you can optionally ...
* use -FailFast to ping machines before trying to query them,
* pass a Credentials object,
* pass a file to 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 * | .\Get-PageFileLocationByWmi.ps1 -FailFast | Format-Table -AutoSize

Jeremy / Justin:  When running the script the results show only one server out of the pulled list of for example 10 servers.  Permissions are correct.  Any thoughts?

oBDA: Where in your script will it know how to pull from a list of servers from a .txt file?

Thanks all!
The script itself doesn't support it, but you can pass it any string array, like the AD example above:
Get-Content -Path C:\Temp\servers.txt | .\Get-PageFileLocationByWmi.ps1 -FailFast -ExportCsv C:\Temp\Pagefiles.csv

Open in new window

Or like this:
.\Get-PageFileLocationByWmi.ps1 -ComputerName (Get-Content -Path C:\Temp\servers.txt) -FailFast
