Specific PowerShell Module Not Autoloading

Im using PowerShell 4 on Windows Server 2012 R2.

A specific module, WebAdministration, does not get auto loaded when calling a Cmdlet that comes from this module. All other modules I have tried auto load successfully. I can load this module manually using Import-Module and it behaves as expected.

  • The PSModulePath environment variable contains the path with the module. Other modules from this path auto load.
  • The module is not custom. It is a built in IIS feature. The feature is enabled.
  • AutoLoading is enabled. $PSModuleAutoLoadingPreference is set to "All"
  • Get-Command "Get-WebBinding" doesn't work, but Get-Command | where {$_.Name -eq "Get-WebBinding"} does.
  • Get-Module -ListAvailable | where { $_.Name -eq "WebAdministration"} returns the module with the correct path.

PSModulePath = %SystemRoot%\system32\WindowsPowerShell\v1.0\Modules\ WebAdministration Module Path = C:\Windows\System32\WindowsPowerShell\v1.0\Modules\WebAdministration



Output from simple test

PS C:\Users\Administrator> $PSModuleAutoLoadingPreference = "All"

PS C:\Users\Administrator> Get-WebBinding Get-WebBinding : The term 'Get-WebBinding' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At line:1 char:1 + Get-WebBinding + ~~~~~~~~~~~~~~ + CategoryInfo : ObjectNotFound: (Get-WebBinding:String) [], CommandNotFoundException + FullyQualifiedErrorId : CommandNotFoundException

PS C:\Users\Administrator> Import-Module WebAdministration

PS C:\Users\Administrator> Get-WebBinding

Any suggestions on why the auto loading isn't working would be greatly appreciated. Thanks!

Have you tried adding it to your PowerShell profile so the import persists outside of your current session? - dfundako
I could resort to that workaround but I'm more interested in the root cause. The auto load functionality should work with this module but it doesn't in my environment. - kareed44
Don't know. Hard to diagnose without your specific paths, variables, or environment info. You have a solution to solve your problem with one line of code in your original post. - dfundako
@kareed44 while I agree that this is annoying and it makes sense to find a root cause, I don't think you should be relying on module auto-loading as anything but a convenience. - briantist
Try to remove everything from %LocalAppData%\Microsoft\Windows\PowerShell\CommandAnalysis and start new PowerShell session. - user4003407

Try reinstalling the module to see if that makes a difference.

If that doesn't work, while it's annoying that the autoload isn't functioning, you can import the module before use and expect it to work.

Import-Module WebAdministration
Get-WebBinding

Or if you need a one-liner:

Import-Module WebAdministration; Get-WebBinding
