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 d

Answer 1

For those on windows server 2016 and 2019 I found that it was the Server Feature

IIS Management Console aka Web-Mgmt-Console

that needed to be turned on. If you are in an active powershell session and have import the WebAdministration module and the command

Get-PSDrive 

does not return IIS in the list. Run the following

Remove-Module WebAdministration
Import-Module WebAdministration
Get-PSDrive

Then you should see the powershell IIS drive. I suspect my issue had to do with running scripts that imported WebAdministration but were attaching the PSDrive IIS in my powershell session. Attempts to import WebAdministration again would not attaching the PSDrive to my session unless I removed it first.

Answer 2

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

Answer 3

To resolve running the script (or powershell shell/exe) in Admin mode.

Answer 4

On Windows Server 2008 32-bit, I had to explicitly download and install "IIS Powershell Snap-in (x86)" from Microsoft's website.

Answer 5

I was facing the same problem while trying to run a script in PowerShell ISE.

The problem was fixed when I reopened PowerShell ISE as Administrator.
