ExecMethod returns WBEM_E_FAILED with CreateZone

Hello everybody,

I'm trying to create a new DNS zone on a MS/DNS server using WMI. Creating
primary zones works fine, but creating secondaries doesn't work, using same
initialization code plus one parameter for the master address : ExecMethod
returns WBEM_E_FAILED, and I can't see the point. I'm not sure if the
problem comes from the initialization of the BSTR[] or an obscure internal
problem. If you can examine the following code, it would be a great help.

Thanks by advance,
Aurelien.
