我正在尝试创建一个powershell函数，它将创建网络上不活动计算机的列表。我不明白我做错了什么，我希望有人能看到我的错误，

Function Get-OldNames {
# to get an accurate list of machines that haven't logged in within a certain amount of time, we need to 
# query all the DCs in the domain then aggregate all the logins together to find the most recent to compare
# against. This function performs that search against the specified OU then returns a list of computer names
# as an array of strings 

    # Set the target OU
    $targetOU = "OU=Computers,OU=NewYork,OU=US,DC=contoso,DC=com"

    # Set the number of days to check for inactive computers
    $inactiveDays = -90
    [System.DateTime]$todaysDate = (Get-Date -Format d)
    $inactiveDate = $todaysDate.AddDays($inactiveDays)
    $inactiveDateValue = (Get-Date $inactiveDate).ToFileTime()

    # Get all domain controllers in the current domain
    $domainControllers = Get-ADDomainController -Filter *

    # Initialize an empty array to hold the results
    $inactiveComputers = @()

    # Loop through each domain controller and query for logons of computers in the target OU
    foreach ($dc in $domainControllers) {
            $dcName = $dc.Name
            Write-Host "Querying $dcName..."
            $inactiveComputers += Get-ADComputer -Filter 'Enabled -eq $true' -SearchBase $targetOU -Server $dcName -Properties LastLogon | Select-Object Name, LastLogon, @{Name='LastLogonAsDate';Expression={[DateTime]::FromFileTime($_.LastLogon)}}
    }

    # Sort the results by last logon time and filter the output
    return $inactiveComputers | Sort-Object LastLogon | Group-Object Name | Where-Object LastLogon -ge $inactiveDateValue | ForEach-Object Name
}

我的错误是，我的列表是空的，无论我设置$inactivedays为，-90，-30，或任何，没有区别。如果将return语句中的过滤器更改为-le而不是-ge，则会获得聚合机器名称的填充列表。我不知道我错过了什么。
