为什么我的登录脚本没有映射任何驱动器？

我在 PowerShell 中编写了一个登录脚本。该脚本嵌入在 GPO 中，并在用户登录域时运行。

我的问题是，我在脚本中部署的驱动器没有被部署。我确信登录脚本会运行，因为在脚本结束时我会向自己发送一封电子邮件，并且我总是会收到它。所以运行脚本应该不是问题。$Error每次脚本运行时，我都会记录整个变量，并且没有迹象表明为什么会发生此错误。

我几乎可以肯定错误不在脚本本身 - 我认为它必须是权限错误。

我认为当我在运行脚本时指定参数时可以解决这个问题-NoProfile，但我不知道将它放在 GPO 的哪个位置。由于美观的原因，我不想要一个调用脚本的批处理文件:-)。

编辑：指定-noprofile没有解决问题

编辑：由于有评论说没有足够的关于如何映射驱动器的信息，我将整个映射部分粘贴在下面：

# UserOU as a parameter, value set in GPO
Param([string]$UserOU)

# preparing some stuff...
Import-Module .\SecureStringFunctions.psm1
[Byte[]]$key = (1..16)
$pw = Get-Content .\LocalAdminCred.txt | ConvertTo-SecureString -key $key

# Tried this to elevate the Script IF it's needed. Didn't solve my problem. works only on PS 4.0 but didn't solve the issue on my 5.0 machine
if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) 
{ Start-Process powershell.exe "-NoProfile -ExecutionPolicy Bypass -File `"$PSCommandPath`"" -Verb RunAs; exit }

# Import CSV with drive information based on username and userOU to get every maps that the current user needs
# also replacing a string inside the CSV for current session to map the homedrive of each user
$Drives = (Get-Content .\NetworkDrives.csv) -replace "userhome",$env:username | ConvertFrom-CSV -Delimiter ';' | ? {
    (($_.Group.split(',') -contains $UserOU) -or ($_.Group.split(',') -contains $env:username)) -and (!(Test-Path $_.Letter))
} 

# When I export the $Drives Variable at this point, all drives were read correctly, so the failure must occur in the mapping

# map all drives for current user. Drives to DMZ with password in plain text because ".mapnetworkdrive" only accepts plain text.
$Drives | % {
    if (![system.string]::IsNullOrEmpty($_.Username)) {
        if (($UserOU -like 'admin*') -and (($_.Server -ne $env:computername) -or ([system.string]::IsNullOrEmpty($_.Server)))) { 
            Continue
        }
        [string]$pwplain = ConvertFrom-SecureString $pw -AsPlainText -Force
        $Map = New-Object -comobject Wscript.Network
        $Map.MapNetworkDrive($_.letter,$_.path,$false,$_.username,$pwplain)
        $pwplain = ""
    } else { 
        $Map = New-Object -comobject Wscript.Network
        $Map.MapNetworkDrive($_.letter,$_.path,$false)    
    }
}
