Using WMI to Join a Domain

[andygunther]

I have the following code that I am trying to use to join a computer to a domain in a C# wizard application I am writing.

I get an unhandled exception from System.Management.dll as soon as I instantiate the ManagementClass (first line).

Has anyone been able to do this in the past? All of the examples I can find are using VBScript - nothing in C#:

try
{
System.Management.ManagementClass mc = new System.Management.ManagementClass("Win32_ComputerS ystem.Name='" + System.Environment.MachineName + "'");
mc.Scope.Options.Authentication = AuthenticationLevel.PacketPrivacy;
mc.Scope.Options.Impersonation = ImpersonationLevel.Impersonate;
mc.Scope.Options.EnablePrivileges = true;

System.Management.ManagementObjectCollection moc = mc.GetInstances();

System.Management.ManagementBaseObject oInputs = mc.GetMethodParameters("JoinDomainOrWorkgroup");

oInputs["Name"] = tbDomain.Text;

oInputs["Password"] = tbPwd.Text;

oInputs["UserName"] = tbUser.Text;

oInputs["AccountOU"] = null;

oInputs["FJoinOptions"] = (UInt32)0x00000011;

System.Management.ManagementBaseObject oResults = mc.InvokeMethod("JoinDomainOrWorkgroup", oInputs, null);

uint ret = (uint)(oResults.Properties["ReturnValue"].Value);

MessageBox.Show(ret.ToString());
}
catch (ManagementException ex)
{
MessageBox.Show(ex.Message + " : " + ex.ErrorCode);
}


Any help is appreciated.

Thanks!

BTW, this is the exception I get:

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in system.management.dll

Additional information: Specified argument was out of the range of valid values.
