exception of type 'System.Managem ent.ManagementE xception'

[Lamis]

Hi,
I need urgent help, this is my code to rename my hostName: (MY computer is
not member of domain)
string compName =
System.Windows. Forms.SystemInf ormation.Comput erName.ToString ();
WqlObjectQuery query = new WqlObjectQuery( "SELECT * FROM
Win32_ComputerS ystem");
ManagementObjec tSearcher search = new ManagementObjec tSearcher(query );
object[] name = {"NewName"};
foreach (ManagementObje ct mo in search.Get())
{
mo.InvokeMethod ("Rename", name);
}

This ex. appears everytime I run my application!

An unhandled exception of type 'System.Managem ent.ManagementE xception'
occurred in system.manageme nt.dll

Additional information: This method is not implemented in any class

thanks in adv.

Note that this only works on XP or W2K3 or higher.

using (ManagementObje ct dir= new
ManagementObjec t("Win32_Comput ersystem.name=' " + Environment.Mac hineName +
"'"))
{
ManagementBaseO bject inputArgs = dir.GetMethodPa rameters("Renam e");
inputArgs["Name"] = "NewName";
ManagementBaseO bject outParams = dir.InvokeMetho d("Rename", inputArgs,
null);
uint ret = (uint)(outParam s.Properties["ReturnValu e"].Value);
if(ret == 0)
// OK
else
// Failed
}

Hi Willy,,

Yes I noticed.. I have win2000 installed on the machine but it works
perfectly on other machines with XP installed.

Thank you for helping
