Question

I m试图从我们每个域控制员那里为每个用户检索自动取款财产<代码>。由于时间有限,Im试图使用Parallel 在PowerShell 7号专栏

Example

$users = Get-ADUser -Filter "[filter]"
$DCs = Get-ADDomainController -Filter * | Where-Object { $_.Site -in $using:sites }

$users | ForEach-Object -ThrottleLimit 2  -Parallel {    
    $serv = $using:DCs

    foreach ($DC in $serv) {
        $lastLogonAD = Get-ADUser -Identity $_ -Properties LastLogon -Server $DC -ErrorAction Stop | Select-Object -ExpandProperty LastLogon

        $lastLogonConverted = [datetime]::FromFileTimeUTC($lastLogonAD)
    }
}

Error

Get-ADUser: 
Line |
   7 |  …        $lastLogonAD = Get-ADUser -Identity $_ -Properties LastLogon -Server  …
     |                ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | The server has returned the following error: invalid enumeration context.

我发现的是,如果我删除<条码>-Server<>>>参数,它就会发挥作用,或者如果我不将财产储存成一个变数,它就会发挥作用。

Removing the server parameter

    foreach ($DC in $DCs) {
        $lastLogonAD = Get-ADUser -Identity $_ -Properties LastLogon -ErrorAction Stop | Select-Object -ExpandProperty LastLogon

        $lastLogonConverted = [datetime]::FromFileTimeUTC($lastLogonAD)
    }

Not storing the variable

    foreach ($DC in $DCs) {
        Get-ADUser -Identity $_ -Properties LastLogon -Server $DC -ErrorAction Stop | Select-Object -ExpandProperty LastLogon

        $lastLogonConverted = [datetime]::FromFileTimeUTC($lastLogonAD)
    }

错误“服务器已退回了以下错误:错误的点数环境”主要因为你的代码非常低,而这一错误出现在问询上长达30多分钟。 See TechNet article 。

Your parallel loop should be running per Domain Controller instead of per User. The parallel invocations should be processing all users per runspace.

如下文法:

Get a list of DistinguishedNames that will be processed in parallel.
Start parallel invocations per Domain Controller and pass that list of DistinguishedNames to process per parallel invocation.
Then group all results by DistinguishedName, sort each group by LastLogon and pick user on each group with the latest LastLogon.
Lastly, project the object with a constructed "friendly" property LastLogonDate.

$sites = # needs to be defined here...

# only need the users `DistinguishedName` here
$users = (Get-ADUser -Filter  [filter] ).DistinguishedName

# parallel loop per DC instead of per user
Get-ADDomainController -Filter * |
    Where-Object { $_.Site -in $sites } |
    ForEach-Object -Parallel {
        $using:users | Get-ADUser -Properties LastLogon -Server $_
    } |
    Group-Object DistinguishedName |
    ForEach-Object {
        $_.Group | Sort-Object LastLogon -Descending -Top 1 |
            Select-Object *, @{ N= LastLogonDate ; E={ [datetime]::FromFileTimeUtc($_.LastLogon) }}
    }
