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    Use Invoke-Command 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

Fairly new to using PowerShell  think I might be able to help  Could you try this   I believe you re not getting the correct parameters to your script block   param  string  one   string  two   res   Invoke-Command -Credential  migratorCreds -ScriptBlock  Get-LocalUsers -parentNodeXML  args 0  -migratorUser  args 1    -ArgumentList  xmlPRE   migratorCreds

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

I was solving same problem recently  I was designing a write cmdlet for my Subtitle module  I had six different user stories    Subtitle only Subtitle and path  original file name is used  Subtitle and new file name  original path is used  Subtitle and name suffix is used  original path and modified name is used   Subtile  new path and new file name is is used  Subtitle  new path and suffix is used    I end up in the big frustration because I though that 4 parameters will be enough  Like most of the times  the frustration was pointless because it was my fault  I didn t know enough about parameter sets    After some research in documentation  I realized where is the problem  With knowledge how the parameter sets should be used  I developed a general and simple approach how to solve this problem  A pencil and a sheet of paper is required but a spreadsheet editor is better    Write down all intended ways how the cmdlet should be used    user stories  Keep adding parameters with meaningful names and mark the use of the parameters until you have a unique collection set    no repetitive combination of parameters  Implement parameter sets into your code  Prepare tests for all possible user stories  Run tests  big surprise  right    IDEs doesn t checks parameter sets collision  tests could save lots of trouble later one    Example      The practical example could be seen over here   BTW  The parameter uniqueness within parameter sets is the reason why the ParameterSetName property doesn t support  String     It doesn t really make any sense

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
