I'm working with DNS resource records in Powershell 5 using code that I inherited from the guy who was trying to do this before me. The cmdlet I am trying to use is Add-DnsServerResourceRecordA.
Part of his code has import-module certain folder\PowerShell\Modules\DnsServer. The weird thing is, it seems like as I was trying bits and pieces of the code earlier, I was able to use the add-DNSblah cmdlet. Now, after It ried running the whole script including the import-module, Powershell is saying that the cmdlet does not exist natively, and when I import the module and run it it is giving me Add-DnsServerResourceRecordA: Invalid Class.
It is my understanding that Add-DnsServerResourceRecordA should be included in my normal Powershell 5.0. Could that Import-Module have permanently damaged PS somehow? Why else would the cmdlet not show up, even in a Get-Command "dns"?
I'm pretty sure you will need the Remote Server Administration Tools (RSAT) installed to have these cmdlets available on a non-server Windows OS.
You can download them from this page: https://www.microsoft.com/en-gb/download/details.aspx?id=45520.
Not really sure why the Import-Module does not fail if the DNSServer module is not present on the system.
If RSAT are already installed, you can try to reinstall them.

I have a machine i would like to install a module on, specifically SwisPowerShell for working with SolarWinds. Internet is disabled on it so i cant use install-module, so i manually downloaded the .nupkg from another machine and went through the steps of unpacking the files into the correct folders. https://learn.microsoft.com/en-us/powershell/scripting/gallery/how-to/working-with-packages/manual-download?view=powershell-7.2. all the .dll files and the windows powershell datafile i have tried in both directories "C:\Program Files\WindowsPowerShell\Modules\SwisPowerShell\3.1.0.343" and "C:\Users\username\Documents\WindowsPowerShell\Modules\SwisPowerShell\3.1.0.343". Importing the module with "import-module -name SwisPowerShell -Global -force -Verbose" shows that everything loads correctly, but then running "get-module SwisPowerShell -Verbose" returns nothing. even loading each dll individually with "add-type -path "C:...\somefile.dll" shows nothing. running "get-module -ListAvailable" shows the module in both (or either) directories as they should be. using "get-help cmdletname" and "get-command cmdletname" shows the correct cmdlet definitions. trying to run any of the cmdlets returns "The term 'connect-swis' is not recognized as the name of a cmdlet, function... yada yadda" for all of the cmdlets. its like powershell sees the files but refuses to use them. Am i missing a step that tells powershell that this is a valid module to use? could it be blocked somehow? what extra steps does install-module do that a manual install does not that i could try?
Try running process monitor while installing on another machine. You might find out it's doing some registry changes too.
I have a custom PowerShell module with two cmdlets. I have it successfully, but manually, deployed on my machine. However, I deployed it by placing the binary file and module manifest in a location, and then registering the module. I also had to manually write an Import-Module command into my 'all users' profile.
Now I am sure I can deploy this module with Publish-Module, but how do I get the Install-Module to write the Import-Module statement to the profile file?
As of PowerShell 3.0, a module is automatically imported when a command from the module is invoked. This was a brilliant on Microsoft's part; however, it did require that modules are located in a location where PowerShell looks for modules by default. Makes sense. You can see those locations by running the following command:
$env:PSModulePath -split ';'
Is there a reason you'd rather not use one of the paths stored in the above environmental variable? That said, I'd keep your code out of the "C:\Windows\System32..." path. The other options are better: "C:\Program Files\PowerShell\Modules" (AllUsers) and "C:\Users\tommymaynard\Documents\PowerShell\Modules" (CurrentUser). Depending on your PowerShell version/OS, those path could be different. You won't need to write an Import-Module command into a $PROFILE script if you get the module into a preferred location. Maybe you already know this, but maybe not.
You're not going to get Install-Module to write to any of the $PROFILE scripts.
$PROFILE | Select-Object -Property *
Well, not by default anyway. You could write your own Install-Module function, that runs PowerShellGet's Install-Module function, and includes writing to various $PROFILE scripts. The problem is that you'll need to include logic so you don't blow away the contents of someone's $PROFILE script if it's not empty, and only append to it.
Seriously though, this is turning into a lot of work, when you could drop the module into a location where PowerShell can find it on its own.
Edit: It just occurred to me, you can add a value/path to the $env:PSModulePath environmental variable. It's a single string with semi-colon delimiters:
$env:PSModulePath.GetType().Name
Therefore, it'd look like this:
$env:PSModulePath += ';C:\Another\Path'
That's great and all, but again how might you stage this, right? It takes you back to the write-to-all-the-$PROFILE-scripts problem,... although you may be able to update the variable via Group Policy Preferences. Again, probably better to just relocate your module.
I am creating a pool in F5.
i came across the below link which gives a function of creating a Pool.
(https://www.powershellgallery.com/packages/f5-ltm/1.4.154/Content/Public%5CNew-Pool.ps1)
All the things are fine. i have installed F5-LTM module for powershell also.
Install-Module -Name F5-LTM -RequiredVersion 1.4.280
I am not able to see the "New-F5Item" cmdlts.
Can you please let me know about this cmdlet.
Thank you
If you look at the file list in PSGallery, you'll notice that the package contains the script file Private\New-F5Item.ps1, indicating that New-F5Item is probably not exported by the module.
When a command is not exported, it can only be discovered/called from other functions in the same module - which is why you don't see it when doing Get-Command or similar.
Windows 8.1, PowerShell 4. I'm wanting to use PS to manage the GAC. I find lots of references to Get-GacAssembly for reading a list, getting detailed info, etc.
But running PS as administrator, and PS ISE, I get an error:
>
The term 'Get-GacAssembly' is not recognized as the name of a cmdlet
Do I need to CD to somewhere? How would I discover where to go to find the cmdlets?
The general answer to your question is that you must first install the module (by adding relevant files to Documents\Powershell\Modules or Windows\System32\WindowsPowershell\v1.0\Modules. Then, you should use Import-Module to load the cmdlets. Cmdlets in Windows\System32\WindowsPowershell\v1.0\Modules should be loaded by default. Script modules (e.g., modules that export functions) require at least RemoteSigned execution settings to run.
I have modified a script to standardise our organisations signatures in Outlook. The script uses a Word document as a template for the signature and extracts user details from the Active Directory info on our SBS 2003 server.
I am logged in as a Domain Admin and the script works ok for my Outlook signature (there are a couple of errors but it creates the 3x outlook signature files that I need). I can't get it to run on any other computer (but this is the only one with Powershell installed) nor will it run for any other user on this computer.
I would really like to be able to run the script from each workstation. This would be easy if it was a batch file, but it won't work as a powershell script. Do I need to install Powershell on every workstation or is there a simpler way to get it to work?
Also,
I wonder if there is a problem with the script that is not allowing other users to run it from this computer (even with Powershell installed).
Cheers,
Greg
Yes, you need Powershell installed on every machine where you want the script to run. It's included with OS on everything from Server 2008 and Windows 7, but otherwise you'll need to install Powershell manually.
You will also have to enable remote scripting on each machine, since this is disabled by default (for security reasons). Take a look at the following help pages for information and instructions on how to set up:
Get-Help about_remote
Get-Help about_remote_FAQ
Get-Help about_remote_requirements
Get-Help about_remote_troubleshooting
If you want to use PowerShell remotely you will need to install it. If you don't want to do that you could look at psexec - that's one of Sys Internals great tools. It will enable you to run commands\scripts remotely.
I have a different suggestion. Could you generate these signature files for your employees on your machine and then push the signatures out to all the other machines?
