Hi there, I would like to know, if is possible to install new protocol to specific network interface other way than: ------------------------------------------------------------- - open the configuration panel for the network card in use (either right click on the icon on the SYSTRAY, or go to Control Panel -> Network and select one card) - click on Properties->Install->Service->Add - click on 'Driver Disk' and select 'protocol.inf' in this folder - select 'this_protocol' which is the only service you should see - click accept on the warnings for the installation of an unknown driver (roughly twice per existing network card) -------------------------------------------------------------- I play a bit with devcon.exe but this does not seems to be good way. Is there any other? Petr Laznovsky
