I'm new to powershell and am trying to write a program that will get the product key of numerous servers.
I am looping through the server names and trying to do the following code but am getting the error in the title
$LicenseInfo = Get-WmiObject -Class SoftwareLicensingProduct -ComputerName $target -Credential $cred | `
Where-Object { $_.PartialProductKey -and $_.ApplicationID -eq "55c92734-d682-4d71-983e-d6ec3f16059f" } | Select-Object PartialProductKey, Description, ProductKeyChannel, #{ N = "LicenseStatus"; E = { $lstat["$($_.LicenseStatus)"] } }
Any help would be appreciated
That error is very specific. Are you targeting machines that do not have this class available? As per learn.microsoft.com for SoftwareLicensingProduct:
Minimum supported client: Windows 7
Minimum supported server: Windows Server 2008 R2

Here's the simple script:
$groups = Get-WMIObject -Class Win32_GroupUser -ComputerName $server | Select-object #{N="Group";E={($_.PartComponent -split "Name=")[1].Replace('"','')}}
$groups
However, $groups is null!
I've checked the interwebs and cannot find a solution.
I'm sure there's a simple answer...
Query is syntactically correct. Check if you are storing the correct value in the $server parameter and that your WMI service is running.
Nothing wrong with what you have here, as it pulls the data when I test this.
Note I am using my localhost, not a remote system here.
(
$groups = Get-WMIObject -Class Win32_GroupUser -ComputerName $env:COMPUTERNAME `
| Select-object #{N="Group";E={($_.PartComponent -split "Name=")[1].Replace('"','')}}
)
Group

postanote
...
IUSR
...
SYSTEM
...

$groups.Count

And fine on a remote system.
(
$groups = Get-WMIObject -Class Win32_GroupUser -ComputerName 'ws01' `
| Select-object #{N="Group";E={($_.PartComponent -split "Name=")[1].Replace('"','')}}
)
Group

So, something environmental in your environment, is the catch 22 for you.
Run this on your localhost host and see if you can get anything back from your targets.

I have this function I'm using a foreach statement block to run against a number of machines:
function Get-InstalledApps ($appStr) {
$appWC = "*$appStr*"
if ([IntPtr]::Size -eq 4) {
$regpath = 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*'
}
else {
$regpath = #(
'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*'
'HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*'
)
}
$getapps = Get-ItemProperty $regpath | .{process{if($_.DisplayName -and $_.UninstallString) { $_ } }}
Foreach ($app in $getapps | where {$_.DisplayName -like $appWC}) {
[pscustomobject]#{Computer = ($env:COMPUTERNAME + "." + $env:USERDNSDOMAIN)
AppName = ($app.displayname)
Publisher = ($app.Publisher)
DisplayVersion = ($app.DisplayVersion)
InstallDate = ($app.InstallDate)
UninstallString = ($App.UninstallString)}
}
}
Locally, it looks like this:
PS C:\windows\system32> Get-InstalledApps ibm | ft
Computer AppName Publisher DisplayVersion InstallDate UninstallString

But when run remotely on some computers
(i.e:)
Invoke-Command -ComputerName $computer -ScriptBlock
${function:Get-InstalledApps} -ArgumentList $appStr
I get the above, however on others I get this:

Without having a chance to verify PowerShell versions of some of the computers yet, I'm guessing the 2nd set of results may be as a result of being run against computers running < version 3.0.
Any way to force the output to display as a table (1st example output) on all computers?
I'm guessing the 2nd set of results may be as a result of being run against computers running < version 3.0.
If you are running that on systems that are not at least version 3 then your [pscustomobject] cast would fail since that was introduced in v3. I would have expected that to just trigger an error but instead it appears to be returning the hashtable. A compatible solution would be to use new-object instead.
New-Object -TypeName PSCustomObject -Property #{
Computer = ($env:COMPUTERNAME + "." + $env:USERDNSDOMAIN)
AppName = ($app.displayname)
Publisher = ($app.Publisher)
DisplayVersion = ($app.DisplayVersion)
InstallDate = ($app.InstallDate)
UninstallString = ($App.UninstallString)
}
Thanks Matt.
That worked, which is my preferred method.
if the app wasn't installed or the host was offline, a couple of variations of IF statements didn't seem to pick up the output at another point in the script (only displayed if it was installed) and returned as a blank line, however this seemed to be picked up by the statement blocks:
function Get-InstalledApps ($appStr) {
$appWC = "*$appStr*"
if ([IntPtr]::Size -eq 4) {
$regpath = 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*'
}
else {
$regpath = #(
'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*'
'HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*'
)
}
$getapps = Get-ItemProperty $regpath | .{process{if($_.DisplayName -and $_.UninstallString) { $_ } }}
$getapps | where {$_.DisplayName -like $appWC} | Select #{n='Computer';e={$env:COMPUTERNAME + "." + $env:USERDNSDOMAIN}},Displayname,Publisher,DisplayVersion,InstallDate,UninstallString
}
I have many servers I need to remove Symantec Endpoint Protection from. I contacted Symantec and received the code below:
(Get-WmiObject -Class Win32_Product -Filter "Name='Symantec Endpoint Protection'" -ComputerName xxxxxx).Uninstall()
I have used it and it worked on 10 servers no problem at all. I tried it again today and am getting the error:
You cannot call a method on a null-valued expression.
At line:1 char:1
+ (Get-WmiObject -Class Win32_Product -Filter "Name='Symantec Endpoint Protection' ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : InvokeMethodOnNull
Nothing has changed from when I started and am trying to figure out what the above error means. Also if I can get this to work does anyone see a way to add many servers to a foreach command or something.
Two things from my side:
1) you should not use win32_product cause it is broken to a certain level.
It is very slow alsso because it scans the entire thing.
2) In your case, "Name='Symantec Endpoint Protection'" reports Null for you which means that the value is not there. Please check the proper name.
For better performance and as part of enhancement , you should use the registry to fetch the details.

Hope it helps.
I am generating a report where I need to find which servers has mountpoints configured on it..
can you help how to get that infor using WMI or powershell.
I mean I need to identify the servers, if mountpoints exists in it.. and also their names....
Get a list of all servers from textfile, AD, etc. and run a foreach loop with something like this:
Get-Wmiobject -query “select name,driveletter,freespace from win32_volume where drivetype=3 AND driveletter=NULL” -computer servername
A quick google search for "windows mount point wmi" would return THIS (source).
Then export the results to CSV, HTML or whatever you need. Your question is lacking a lot of details and any sign of effort from your part, so I can't/won't go any further.
UPDATE: Does this help? It lists mount points(folder paths, not driveletters).
$servers = #("server1","server2","server3","server4","server5")
$servers | % {
$mountpoints = #(Get-WmiObject Win32_MountPoint -ComputerName $_ | Select-Object -ExpandProperty Directory | ? { $_ -match 'Win32_Directory.Name="(\w:\\\\.+)"' }) | % { [regex]::Match($_,'Win32_Directory.Name="(\w:\\\\.+)"').Groups[1].Value -replace '\\\\', '\' }
if($mountpoints.Count -gt 0) {
New-Object psobject -Property #{
Server = $_
MountPoints = $mountpoints
}
}
}

I am using HyperV WMI provider to to update virtual machine's configuration/settings (like hard ware, disks etc..)
How can I get IpAddress of a VM from HyperV?
How to do the same thing in VMWare?
Regards,
Dreamer!
This article describes how to get the IP address of a virtual
machine from Hyper-V (Windows 2008 R2 Hyper-V) using Powershell.
Using the PowerCli: (get-vm <name of your vm>).guest.ipaddress
For Hyper-V, this is how I usually pull an IP from a host box.
$vm = Get-WmiObject -computerName "." -NameSpace "Root\Virtualization" -query "SELECT * FROM Msvm_KvpExchangeComponent" #pulls VM WMI object ExchangeComponents
$vmitems = $vm.GuestIntrinsicExchangeItems
$ipitem = $vmitems[-4]#yay! a hack that relies on XML schemas!
$xmlip = [xml]$ipitem #convert string format to XML
$ipaddr = $xmlip.INSTANCE.PROPERTY[1].VALUE #playing with XML schemas again hopefully reliably
It's not the neatest/cleanest/nicest code, but it is a way to get that information.
Here's an alternate variation that I cooked up to demonstrate a more robust approach at finding the value for a given name. This doesn't rely on a specific relative ordering inside the schema of Caption, Data, Description, ElementName, Name or Source
$vmParams = #{
NameSpace = 'Root\Virtualization';
Query = 'SELECT * FROM Msvm_KvpExchangeComponent' #pulls VM WMI object ExchangeComponents
}
Get-WmiObject #vmParams |
% {
$xml = [Xml]"<properties>$($_.GuestIntrinsicExchangeItems)</properties>"
$xml.properties.INSTANCE.Property |
% {
$value = ($_.ParentNode.Property | ? { $_.Name -eq 'Data' }).VALUE
if ($_.Value -eq 'FullyQualifiedDomainName')
{
Write-Host "Host: $($value)"
}
if ($_.Value -eq 'RDPAddressIPv4')
{
Write-Host "RDP Address: $($value)"
}
}
}
