Hi,


I wrote an NDIS IM filter driver. When i run this driver on windows xp
then NDIS is constantly calling OID_GEN_LINK_SPEED.
When i run the same driver on windows 2003, then it is constantly
calling OID_GEN_RCV_OK and OID_GEN_RCV_NO_BUFFER but not
OID_GEN_LINK_SPEED.
why?

systray is not showing any LAN connection, still getting this OIDs.

Is there any way to reduce this?


Thanks in advance

Gaurav

No way (or need) to reduce this behavior. These are automatically generated
by Microsoft TCP/IP stack to monitor the health of the lower-level miniport.

I beleive there is no polling in Vista. Miniports are required to
indicate status.
