WMI classes for NDIS OIDs

NTDEV
1

Hi,

I have been trying to find a way to set/get NDIS OIDs using WMI (Windows
Management Instrumentation) for some advanced features in Windows 2003/2008
like OID_TCP_OFFLOAD_CAPABILITIES, OID_TCP4_OFFLOAD_STATS etc. The wbemtest
gives a list of classes for NDIS where I found a set of WMI classes to
access the other NDIS parameters like Mediaconnectstatus and other adapter
features. But I am unable to find any class in WMI in order to get/set
features like TCP checksum offload, RSS, HDS etc.

But when I used a tool called OIDScope, I was able to see the OIDs for the
TCP offload but not for HDS and RSS.

Are you aware of any WMI classes which would help me in getting these
parameters using a VBscript at user space ?

Thank you

Not every NDIS OID has a matching WMI class. This is normal.

Thanks Pavel. Is there any other way through which I can access these
parameters from user space (other than using device manager)?
Thanks,

I would think you could set these properties either through the registry or
the netsh tool, although the latter isn’t really a programmatic approach if
that’s what you’re looking for.
