无法使用 C# 远程运行管理 PowerShell 命令

我正在尝试运行远程PowerShell脚本来查询并终止在特定会话中运行的任务：

string hostname = "XADCG.mydomain.co.uk";
string script = "$pw = convertto-securestring -AsPlainText -Force -String password123 " + Environment.NewLine +
                "$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist '"DOMAIN1''zzkillcitrix'",$pw" + Environment.NewLine +
                "$sessions = New-PSSession -ComputerName " + hostname + " -credential $cred" + Environment.NewLine +
                "Invoke-Command -session $sessions -ScriptBlock {taskkill /s xa7-11.mydomain.co.uk /PID 26208 /F}" + Environment.NewLine +
                "Remove-PSSession -Session $sessions" + Environment.NewLine +
                "exit";
// Create and open runspace  
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
// Create piepeline and feed it the script text
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(script);
Collection<PSObject> results = new Collection<PSObject>();
try
{
    results = pipeline.Invoke();
    var error = pipeline.Error.Read();
}
catch (Exception ex)
{
    results.Add(new PSObject((object)ex.Message));
}
runspace.Close();

如果我调用 tasklist ，我会在 results 变量（服务器 XADCG 上运行的进程列表）中获得正常的预期结果

但是，如果我尝试对另一个会话（例如 query session user.name /server:xa11.mydomain.co.uk）运行查询，我的结果变量返回空

检查输出哪些错误后，我发现了以下内容：

taskkill /s xa11.mydomain.co.uk /pid 5876 /F
    {ERROR: Logon failure: unknown user name or bad password.}
query session user.name /server:xa11.mydomain.co.uk
    {Error 5 getting sessionnames}
tasklist /s xa7-11.mydomain.co.uk /fi '"SESSION EQ 4'"
    {ERROR: Logon failure: unknown user name or bad password.}

这显然使我似乎使用了错误的用户名/密码，但我 100% 确定这些在 $cred 变量中设置正确

我还可以确认帐户zzkillcitrix确实有权远程运行这些查询（我能够通过为此用户使用runas调用Process.Start来执行所有这些命令）

是否有其他地方需要设置这些凭据，或者我的脚本中缺少其他内容？

感谢对此的任何帮助
