# Powershell Script help

Posted on 2015-02-09

Hi

I need to check who is logged onto various Blade Workstation's using a Powershell Script and output to a text file so that we can then format the text file to HTML using Powershell

We use this to help Users see what Blades are available who is logged in if they require a certain Blade.

I have used a .bat file in the past and cleaned the output file in Powershell, But would like to clean up the process with just one script.

One issue I have found when looking online for a solution is the ability to have the UserName field show as "No Users" when No user is logged on.

We use the "No User" to assign a Blade is Free icon in the HTML page.

I have tried to use the eq $Null but have failed so far. Requirements Hostname UserName + "No User" Time logged in Any help on finding a solution would be very much appreciated.

Testing against $Null works for me. But we can also do it the other way round: gwmi -computer (gc c:\temp\ee\computers.txt) Win32_ComputerSystem | select @{n='Blade'; e={$_.Name}},
@{n='User'; e={ if ($_.UserName) {$_.Username } else { "No user" }} }

Getting login time is more complex. You need to query Win32_LogonSession with the logon ID, which is associated to the name by another WMI object I cannot remember ...

Hi Qlemo

Login time isn't that important so it can be removed.

Is there away to have the USERNAME in Uppercase

DE-PROD\bendb = DE-PROD\BENDB

Thank you for your help with this, your time and effort is very much appreciated

any ideas how we can deal with the following error

Get-WmiObject : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

we have an issue with the Blade and it would be good to assign an "issue" symbol on the HTML page

Thank you
