我试图在另一台电脑上运行命令，但在运行代码时一直出现此错误。
我已经启用了Windows Management Instrumentation（Windows管理规范）的域管理，就像这篇文章

var hostname = "myIP"; //hostname or a IpAddress

 var connection = new ConnectionOptions();
 //The '.\' is for a local user on the remote machine
 //Or 'mydomain\user' for a domain user
 connection.Username = "myUsername";
 connection.Password = "Mypass";
 connection.EnablePrivileges = true;
 connection.Impersonation = ImpersonationLevel.Impersonate;
 connection.Authority = "ntlmdomain:" + "myworkgroup";
 connection.Authentication = AuthenticationLevel.Packet;

 object[] theProcessToRun = { anyCommand };

 var wmiScope = new ManagementScope($@"\\{hostname}\root\cimv2", connection);
 wmiScope.Connect();

我还可以确认另一台PC已打开并连接到Internet（与我运行C#程序的PC相同的Internet）
你知道我还错过了什么吗？
