Invoke-Command error "Parameter set cannot be resolved using the specified named parameters"

Question

Hope you can help me with a problem trying to execute a script block with alternate credentials on a local computer. I've been thoroughly searching on forums and doing some googling and found two possible approach to solve my problem:

1. Use Invoke-Command
2. Use Start-Job

Using approach #1 I had this code:

$res = Invoke-Command -Credential $migratorCreds -ScriptBlock {param($one, $two) Get-LocalUsers -parentNodeXML $one -migratorUser $two } -ArgumentList $xmlPRE,$migratorCreds 

where Get-LocalUsers is a custom function stored in a custom module (*.psm1).

My problem is that every time I run this code I get following error:

Parameter set cannot be resolved using the specified named parameters

So it's obvious that I must be missing something, could you help me on this topic?

Thanks in advance...

Answer 1

The error you have is because -credential without -computername can't exist.

You can try this way:

Invoke-Command -Credential $migratorCreds  -ScriptBlock ${function:Get-LocalUsers} -ArgumentList $xmlPRE,$migratorCreds -computername YOURCOMPUTERNAME 

Answer 2

The accepted answer is correct regarding the Invoke-Command cmdlet, but more broadly speaking, cmdlets can have parameter sets where groups of input parameters are defined, such that you can't use two parameters that aren't members of the same parameter set.

If you're running into this error with any other cmdlet, look up its Microsoft documentation, and see if the the top of the page has distinct sets of parameters listed. For example, the documentation for Set-AzureDeployment defines three sets at the top of the page.
