Rename my Computer

[Lamis]

HI,

I need to install a service that changes Host Name, computer name, on all
our machines.
I have tried to ways:
First one:
static void RenameHostName( )
{
ManagementClass mComputerSystem = new ManagementClass
("Win32_Compute rSystem");
ManagementBaseO bject objNewComputerN ame =

CoomputerSystem .GetMethodParam eters("Rename") ;
Console.WriteLi ne(objNewComput erName["Name"]);
objNewComputerN ame["Name"] = "NewHostNam e";
Console.WriteLi ne(objNewComput erName["Name"]);
mComputerSystem .InvokeMethod(" Rename",objNewC omputerName,nul l);
}

Second way
static void RenameHostName2 ()
{
using(Managemen tObject cs = new
ManagementObjec t(@"Win32_Compu tersystem.Name= 'myHostName'"))

{

cs.Get();

ManagementBaseO bject inParams = cs.GetMethodPar ameters("Rename ");

inParams["Name"] = "NewHostNam e";

ManagementBaseO bject outParams = cs.InvokeMethod ("Rename", inParams,
null);

// Check return value ...

uint ret = (uint)outParams .Properties["ReturnValu e"].Value;

}
}

None of these has worked, my hostName is still the same..... Do I have to
restart my computer after changing hostName or will the the system change
without restarting my computer???

is there any other way to change host name??? All new Ideas are very
appreciated.

I know that if you change the computer name manually, you have to
restart the computer.
