Re: How to stop WZC Service in XP-SP2

With some patience debugging of my app, I found the following..

When I stop the service, I dont get Error 170 anymore (though I dont do all
this stuff for disabling a particular NIC). I just do "net stop wzcsvc". But
without "net stop" and just by trying WZCSetInterface, doesn't make any
difference (It gives error 170).

OK, now that I know by doing "net stop", I could get rid of error 170, I'm
trying to SET NDIS_802_11_SSID. Here I get error 2 ("The system cannot find
the file specified"). Is this something related to the fact that I didn't
disable NIC using WZCSetInterface or something else?

This is what I'm doing to SET NDIS_802_11_SSID..
1. hNdis = CreateFile("\\\\.\\\\Ndisuio", ...); //SUCCESS
2. DeviceIoControl (hNdis, IOCTL_NDISUIO_BIND_WAIT, ...); //SUCCESS
3. DeviceIoControl (hNdis, IOCTL_NDISUIO_OPEN_DEVICE,
L"\\DEVICE\\{CBBD6910-2191-4E07-8F88-6AB5FAABFE9B}", ...);
//SUCCESS (after "net stop")
4.
UCHAR buffer[sizeof(NDISUIO_SET_OID) + sizeof(NDIS_802_11_SSID)] = {NULL};
NDISUIO_SET_OID* poid = (NDISUIO_SET_OID*)buffer;
poid->Oid = OID_802_11_SSID;
memcpy(&poid->Data, &ndis, sizeof(NDIS_802_11_SSID));
DeviceIoControl (hNdis, IOCTL_NDISUIO_SET_OID_VALUE, poid,
sizeof(NDISUIO_SET_OID)+sizeof(NDIS_802_11_SSID), ...);
// This gives me Error 2.

Any ideas please?

Thanks,

- John.
