Powershell issues with app pool restart schedule - powershell

Question

This is the first thing I have ever done with Powershell. The gist of the script is to do some base setup for my companies web server installation. Basically it should
Take a list of names
Make a user with that name
configure user make a folder with that name
make an application pool with that name
set application pool properties
set folder permissions for a group
The code is below.
Import-Module WebAdministration
#$apps = #('H','N1','N2')
foreach ($app in $apps){
## I need to check for if a user exists first
NET USER $app "password" /ADD
NET LOCALGROUP "iis_iusrs" $app /ADD
WMIC USERACCOUNT WHERE "Name=$app" SET PaswordExpires=False
#See if the application's folder exists
if (!(Test-Path("C:\inetpub\wwwroot\"+$app)))
{
New-Item -ItemType Directory -Force -Path C:\inetpub\wwwroot\$app
}
## See if the application Pool exists. If it doesn't then create it
if (!(Test-Path("IIS:\AppPools\"+$app)))
{
$appPool = New-Item ("IIS:\AppPools\"+$app)
$appPool.ProcessModel.identityType = 3
$appPool.ProcessModel.userName=$app
$appPool.ProcessModel.password="password"
$appPool.ProcessModel.idleTimeout=[TimeSpan]::FromMinutes(0)
$appPool.processModel.loadUserProfile="True"
$appPool.recycling.disallowOverlappingRotation = "True"
$appPool.recycling.disallowRotationOnConfigChange = "True"
$appPool.recycling.periodicRestart.time = [TimeSpan]::FromMinutes(0)
$appPool | Set-Item
$propPath = "IIS:\AppPools\"+$appPool
New-ItemProperty -Path $propPath -Name recycling.periodicRestart.schedule -Value #{value="00:06:00"}
}
}
$webserver = Hostname
if(!(Test-Path("C:\"+$webserver)))
{
$hostserver = Read-Host "What is the host server's name?"
New-Item -ItemType Directory -Force -Path C:\$webserver\$hostserver
}
if(!(Test-Path('C:\Temp')))
{
New-Item -ItemType Directory -Force -Path C:\Temp
}
$Acl_inetpub = Get-Acl C:\inetpub
$Acl_temp = Get-Acl C:\Temp
$Acl_windows_temp = Get-Acl C:\Windows\Temp
$Ar_iis = New-Object System.Security.AccessControl.FileSystemAccessRule(".\iis_iusrs","FullControl","ContainerInherit,ObjectInherit","None","Allow")
$Ar_users = New-Object System.Security.AccessControl.FileSystemAccessRule(".\users","FullControl","ContainerInherit,ObjectInherit","None","Allow")
$Acl_inetpub.SetAccessRule($Ar_iis)
$Acl_inetpub.SetAccessRule($Ar_users)
$Acl_temp.SetAccessRule($Ar_iis)
$Acl_temp.SetAccessRule($Ar_users)
$Acl_windows_temp.SetAccessRule($Ar_iis)
$Acl_windows_temp.SetAccessRule($Ar_users)
Set-Acl C:\inetpub $Acl_inetpub
Set-Acl C:\temp $Acl_temp
Set-Acl C:\Windows\Temp $Acl_windows_temp
My issue currently is.
$propPath = "IIS:\AppPools\"+$appPool
New-ItemProperty -Path $propPath -Name recycling.periodicRestart.schedule -Value #{value="00:06:00"}
I get a path error when I run this but I am not sure where the error is coming from. Also, is there a way to do this same thing but just using the object like I did the rest of the settings? So far I have not found a way to do this.

Answer 1

So I found the final issue thanks Randy Schuman's advice. I wasn't thinking about how I was using $app vs $appPool . I was just continuing the pattern of using the $appPool's object when I need to supply it the $appPools name which is just $app. When I switched that it worked.
