Thanks for your replying.
I'll discribe my problem.
We develop PCMCIA cards.
To check throughput using traffic generator (SmartBit foe exs.) needs Eth port for connecting the card side to the traffic generator.
There is not another way as creating Nework Bridge between PCMCIA and another NIC.
The problem is that the card for getting IP from DHCP server and network service must be removed from Bridge, Disabled/Enabled and added to Bridge again. If you work with 20 cards this turns to big problem to do it manually.
How to add / remove NIC to / from Network Bridge in XP programmatically?
Thanks.
