Custom OIDs for WMI in NDIS miniport driver

Hi Experts,
I am trying to add custom OIDs for WMI testing in my NDIS miniport
driver.
I have created MOF file describing the classes and defined and handled
the all the custom OIDs in driver.
I couldn't see my WMI classes in Wbemtest application after loading
the driver. When i try to enumerate the classes I am getting Invalid
Class error. I took the sample from WDK version 6000. The sample is
NDIS/e100bex.
All the WMI standard OIDs I can enumerate except my custom OIDs and
respective classes.

I have seen many posts WRT NDIS Miniport custom OIDs, I haven't found
useful information for on only custom NDIS Miniport OIDs. I hope
somebody will definately help me to get rid of this problem.

Thanks in advance, Your valuable advices/suggestions are always
appreciable.

Have you actually built and installed this driver?

Yes, I have Built and successfully installed the driver.
I din't get you? whats that mean?
I have a NDIS miniport driver working fine without WMI support.
I just started adding WMI stuff with help of E100BEX sample in DDK.
Am I doing something wrong? How can i add WMI support in my Ndis
miniport driver?
Can you suggest me something? How to deal with custom GUIDs?

Thanks in advance

I think there was some OID which needs to return the table of WMI ID -> OID
mapping, after which WMI queries are translated to NdisRequest using this
table.

Hi,
Yes there is an OID called OID_GEN_SUPPORTED_GUIDS which maps all
custom GUIDs with custom IODs.
I traced into the driver, it has created and all GUIDs are mapped with
respective OIDs.
Still I could not see these classes available in WMI CIM studio OR
'wbemtest' application, I get 'Invalid class' error.
thanks in advance.

IIRC, registration of the driver's WMI data occurs
when the NDIS successfully starts the driver first time.

Hi Pavel,
Could you explain me more in detail, when exactly WMI registration
will be done for Ndis Miniport driver and How it will be done.
I am seeing some of the calls are successful such as
OID_GEN_SUPPORTED_LIST and OID_GEN_SUPPORTED_GUID are successful and
returned the list of supported OIDs as well as supported GUIDs.

Hope somebody will correct me, I haven't touched the WMI stuff for a
while...

- First, you write the MOF describing your custom objects.
It contains the GUIDs for these objects. See file e100.mof in the example.

- The mof gets compiled to binary (.bmf) by makefile.inc.
The resulting bmf is then linked into the .sys file: see e100.rc.

- When the driver starts, NDIS detects presense of your WMI stuff
as the driver responds to OID_GEN_SUPPORTED_GUIDS.
It extracts the BMF from your sys file, and patches it into the WMI
plumbing.

IMHO this could be a bit easier, though.
