powershell - Getting "Can't find the drive. The drive called 'IIS' does not exist."

Question

I wrote a PowerShell script to deploy IIS Website automatically, but when I pass parameters to the script I get the following error:

Cannot find the drive. The drive called 'IIS' does not exist.

My script (iss_website_version_update.ps1) is as below, but note that it is not finished yet:

param(
[array]$iishostlist=$(throw "Parameter missing: -name iishostlist"),
[array]$websiteName=$(throw "Parameter missing: -name websiteName")
)

For($i=0;$i -lt $iishostlist.Count; $i++){
For($j=0;$j -lt  $websiteName.Count; $j++){
    $start = get-date
    $tempSession = new-pssession  -ComputerName  $($iishostlist[$i])
    Invoke-Command -Session $tempSession -ScriptBlock {
        C:WindowsSystem32WindowsPowerShellv1.0powershell.exe -NonInteractive -command Import-Module WebAdministration;set-location IIS:;(Stop-Website $($websiteName[$j]))
        }
    .......

Please let me know why the sub-command set-location IIS:; in the command Invoke-Command is not be recognized ?

Answer 1

The drive is provided by the WebAdministration module, so you need to install/import that module first.

How you install the module depends on your actual system and whether you use GUI or PowerShell. On a Windows Server 2008 R2 for instance you'd install the module with the following PowerShell commands:

Import-Module ServerManager
Add-WindowsFeature Web-Scripting-Tools

After the module is installed you can load it in your script like this:

Import-Module WebAdministration
