Why is only one Windows application able to use multicast?

Some network adapter drivers are not able to take direction from more than one application at a time. This is either a hardware or driver bug in the network adapter. This used to be a common problem when multicast was a novelty. Updating the driver for the adaptor may fix the problem, otherwise a new adapter is necessary. We have had a report that the Linksys PC100 Ethernet card will only take direction from one Windows application. The remedy was to replace it with a Linksys Cardbus 10/100.
