WMI SystemDriver

[Ulf]

Hi all,

when trying to use the Win32_SystemDri ver StopService call on an Intel
PRO/1000 network adapter, I always get the return error code <4>. Yet
using the "ChangeStartMod e" to disable or even "StartServi ce" methods
while in manual StartMode works perfectly. I already checked the
AcceptStop property, which returns true.

Honestly I have no idea why calling the StopService method (and
StopService only) returns an error code.

Any ideas ?

thx :)

ManagementClass mc = new ManagementClass ("Win32_SystemD river");

foreach (ManagementObje ct mo in mc.GetInstances ())
{
if (mo["DisplayNam e"].ToString().Ind exOf("PRO/1000") >= 0)
{
ManagementBaseO bject inPar =
mc.GetMethodPar ameters("Change StartMode");
inPar["StartMode"] = "Manual";
ManagementBaseO bject outPar = mo.InvokeMethod ("ChangeStartMo de",
inPar, null);
res += "ChangeStartMod e returns : " +
outPar["ReturnValu e"].ToString() + "\n";
inPar = null;
outPar = mo.InvokeMethod ("StopServic e", inPar, null);
res += "StopServic e returns : " +
outPar["ReturnValu e"].ToString();
}
}
MessageBox.Show (res);
