Powershell 找出断开的 RDP 会话并同时注销

Question

是否有脚本可以从任何服务器注销断开连接的 RDP 会话？这导致了很多痛苦和持续的广告帐户锁定。

任何帮助都会很棒。

Answer 1

我得到了答案，我写这个答案是为了帮助有需要的人，因为我必须自己解决这个问题。我使用在线资源创建了一个脚本，以找出我的 AD 环境中所有 Windows 服务器上断开连接的 RDP 会话。我运行在每个 Windows 服务器上查询并创建一个 CSV 格式的列表，然后我使用该列表从这些服务器注销我的 ID，因此我没有任何断开连接的会话。

我这样做是为了确保我的 AD 帐户在更改密码时不会因为一些断开连接的 RDP 会话而被锁定。

您可以根据需要自由修改此脚本。

脚本代码如下：

param (
        #get current logged on username
        [string]$UserName = $env:USERNAME
    )

    # Import the Active Directory module for the Get-ADComputer CmdLet
    Import-Module ActiveDirectory


    # Query Active Directory for enabled windows servers computer accounts and sort by name
    $Servers = Get-ADComputer -Filter {(OperatingSystem -like "*windows*server*") -and (Enabled -eq "True")} | Sort Name

    # Initiating variables
    $SessionList = $NULL
    $queryResults = $NULL
    $SError = $null
    $SDown = $null
    $z = 0

    # Get total number of servers
    $count = $Servers.count 


    # Start looping through each server at a time
    ForEach ($Server in $Servers) {    

        # initiate counter for showing progress
        $z = $z + 1

        $ServerName = $Server.Name

        # Start writing progress 
        Write-Progress -Activity "Processing Server: $z out of $count servers." -Status " Progress" -PercentComplete ($z/$Servers.count*100)

        # check if server is pingable before running the query on the server
        if (Test-Connection $Server.Name -Count 1 -Quiet) {  

            Write-Host "`n`n$ServerName is online!" -BackgroundColor Green -ForegroundColor Black

            Write-Host ("`nQuerying Server: `"$ServerName`" for disconnected sessions under UserName: `"" + $UserName.ToUpper() + "`"...") -BackgroundColor Gray -ForegroundColor Black

            # Store results in array
            [array]$queryResults += (

                # Query server for specific username
                query user $UserName /server:$ServerName | 
                foreach {
                    # Look for lines with Disc string to filter out active sessions
                    if ($_ -match "Disc") {

                        # format the output in CSV by replacing more than 2 spaces with a comman
                        write-output ("`n$ServerName," + (($_.trim() -replace ' {2,}', ',')))
                    }
                }
            )
        }
        # If server is not pingable show error message
        else {
            # Make list of server that are down.
            [array]$SDown += ($ServerName)
            Write-Host "`nError: Unable to connect to $ServerName!" -BackgroundColor red -ForegroundColor white
            Write-Host "Either the $ServerName is down or check for firewall settings on server $ServerName!" -BackgroundColor Yellow -ForegroundColor black
        }
    }

    # If there are some non pingable server then display the list
    if ($SDown -ne $null -and $SDown) {
            Write-Host "`nScript was unable to connect to the following server:" -ForegroundColor White -BackgroundColor Red
            $SDown
    }

    # Check if any disconnected session are stored in the array
    if ($queryResults -ne $null -and $queryResults) {

        # Convert the CSV fromat to table format with headers
        $QueryResultsCSV = $queryResults | ConvertFrom-Csv -Delimiter "," -Header "ServerName","UserName","SessionID","CurrentState","IdealTime","LogonTime"

        # Show the results on console
        $QueryResultsCSV |ft -AutoSize

        # Go through each Disconnected session stored in the array
        $QueryResultsCSV | foreach {

            # Grabb session ID and ServerName
            $Sessionl = $_.SessionID
            $Serverl = $_.ServerName

            # Show message on the console
            Write-Host "`nLogging off"$_.username"from $serverl..." -ForegroundColor black -BackgroundColor Gray
            sleep 2

            # Logout user using session ID
            logoff $Sessionl /server:$Serverl /v

        }
    }
    else {
        # if array is empty display message that no session were found
        Write-Host `n`n`n`n("*" * $LineSize)
        Write-Host "You are all good! No ghost sessions found!" -BackgroundColor Green -ForegroundColor Black
        Write-Host ("*" * $LineSize)
    }

    # Pause at the end so you can capture the output
    $null = Read-Host "`n`nScript execution finished, press enter to exit!"

当脚本运行在所有服务器上运行时，显示在线和离线服务器：
脚本无法连接的服务器列表：
该脚本列出了它发现断开连接的 RDP 会话的服务器。
当脚本开始记录断开连接的会话并在结束时暂停。

感谢您提供示例代码。我创建了一个简化的代码来注销同一服务器中所有断开连接的用户

$hostname = hostname
if (Test-Connection -ComputerName $hostname -Quiet -Count 1){
    $result = query session /server:$hostname
    $rows = $result -split "`n" 
    foreach ($row in $rows) {   
        if ($row -NotMatch "services|console" -and $row -match "Disc") {
            $sessionusername = $row.Substring(19,20).Trim()
            $sessionid = $row.Substring(39,9).Trim()
            Write-Output "Logging Off RDP Disconnected Sessions User $sessionusername"#, $session[2], $session[3]"
            logoff $sessionid /server:$hostname
        }
    }
}
