public DirectoryEntry Find(string, string) method get Exception from

HRESULT: 0x80005008
public DirectoryEntry Find(string); method get NullReferenceException

source code :
DirectoryEntry rootfolder = new
DirectoryEntry("IIS://localhost/W3SVC/1/ROOT");

Have you checked at this point to make sure "rootfolder" is not
null???

if(rootfolder != null)
{
DirectoryEntry de = rootfolder.Children.Find("docula5",
"IIsWebVirtualDir");//,rootfolder.SchemaClassName);
}
else
{
MessageBox.Show("Your 'rootfolder' is NULL !!");
}

rootfolder is not null.

If I delete the line :
deNewVDir.Invoke("AppCreate",true);
the find method work fine.

rootfolder is not null.

And rootfolder.Children? Does it contain any children at all?
