I am trying to use WMI to execute a command on a remote computer (which I found out how to do), but what I need now is to see the actual result of the command. For example, if I run the ipconfig command I would like to see the result come back to my remote station. Is there any way to do this?

No, not really....

You *could* redirect the output of the command into a local text file, wait a few miliseconds for the file to close, and then read the contents of the file.

Since the redirection actually uses the Command Shell, you'd have to modify your command to look like this:

        wmi = New ManagementClass("\\" & PC & "\root\cimv2:Win32_Process")
        wmi_in = wmi.GetMethodParameters("Create")
        wmi_in("CommandLine") = "cmd /c C:\SomeCommand.exe > C:\Temp\Output.txt"
        wmi_out = wmi.InvokeMethod("Create", wmi_in, Nothing)
        ret = Convert.ToInt32(wmi_out("returnValue"))
        If ret <> 0 Then
            Throw New ApplicationException("Create method error " & ret)
        End If

public String ExecuteRemoteCommands(String computerName, String command)
        {
            String line = null;
            String result = null;
            ConnectionOptions connOptions = new ConnectionOptions();
            ObjectGetOptions objectGetOptions = new ObjectGetOptions();
            ManagementPath managementPath = new ManagementPath("Win32_Process");
            connOptions.Impersonation = ImpersonationLevel.Impersonate;
            connOptions.EnablePrivileges = true;
            try
            {
                ManagementScope manScope = new ManagementScope(String.Format(@"\\{0}\ROOT\CIMV2", computerName), connOptions);
                manScope.Connect();
                ManagementClass processClass = new ManagementClass(manScope, managementPath, objectGetOptions);
                ManagementBaseObject inParams = processClass.GetMethodParameters("Create");
                inParams["CommandLine"] = "cmd /c " + command + " > c:\\tmp.txt";
                ManagementBaseObject outParams = processClass.InvokeMethod("Create", inParams, null);
                Thread.Sleep(5000);
                StreamReader sr = new StreamReader("\\\\" + computerName + "\\c$\\tmp.txt");
                line = sr.ReadLine();
                while (line != null)
                {
                    result += line;
                    line = sr.ReadLine();
                }
                sr.Close();
            }
            catch (Exception exception)
            {
                exception.Message.ToString();
            }
            return result;
        }

Isn't that solution exactly what I had suggested?    Namely, to redirect the output to a file, wait a while, and then read the contents of the file
