Hi Bryan,
While installing the IM driver we see that the driver
is bound to a maximum of two adapters. Apart from
that the system also pops up dialogs like “Your system
allows a maxium of 6 TCP/IP instances” and “Your
system allows a maxium of 8 instances”.
We used the inf sample you had given where some
entries that you might want to know are
Protocol: MaxInstance = 4
Protocol: HKR,Ndi,MaxInstance,8
Miniport: MaxInstance = 8
Miniport: HKR,Ndi,MaxInstance,8
We also tried installing it after changing
MaxInstances to 8, 16, 16, 16 respectively for the
above inf entries. We also changed the max instances
of TCP/IP to 8 in the nettrans.inf file. Even then
the IM driver binds to only two adapters.
So, if there are more than 2 adapters how may we
install and bind our IM driver to all the adapters?
Thanks and regards
Murali
