powershell - WS-Management服务无法处理请求:Powershell

Question

我随机得到以下错误

The WS-Management service cannot process the request. This user is allowed a maximum number of 5 concurrent shells, which has been exceeded. Close existing shells or raise the quota for this user. For more information, see the about_Remote_Troubleshooting Help topic.

我的示例代码如下

try
{
    $serverlist=server1...server100
    foreach($computer in $computers)
    {
    Enter-PSSession -ComputerName $computer

    $Ostype = (Get-WmiObject  -Class Win32_OperatingSystem  -ComputerName $computer -ErrorAction SilentlyContinue ).Caption 

    Exit-PSSession
}
    }
    Catch
    {
    [System.Windows.MessageBox]::Show($_.exception.message)
    }
    finally
    {
    Exit-pssession
    }

在执行脚本的过程中有时会发生错误，因此上述错误使我相信，我没有正确关闭PSsession。

有人可以让我知道我做得对吗

Answer 1

请尝试以下代码。它不使用交互式 session ，而是使用Invoke-Command cmdlet。

try
{
    $serverlist=server1...server100
    foreach($computer in $computers)
    {
    $s = New-PSSession -ComputerName $computer 
    Invoke-Command -Session $s -ScriptBlock {$os = (Get-WmiObject  -Class Win32_OperatingSystem  -ComputerName $computer -ErrorAction SilentlyContinue ).Caption}

     Remove-PSSession -Session $s
    }
}
Catch
{
    [System.Windows.MessageBox]::Show($_.exception.message)
}
