I have a program on one computer that is sending multicast packets. I can see the packets in Wireshark on that same computer, and on a different computer while in Linux, but not while in Windows (it's dual-boot).

The sending computer is wired into a router. The receiving computer is wireless. I'm using the same wireless NIC in both Linux and Windows. Any help would be greatly appreciated!

Is the capturing computer (Windows) wireless? If so, have you checked out this answer?

Thank you, multipleinterfaces. That was exactly the problem.

Just for future people searching: there was actually no problem with the packets being transferred, I simply had to use Microsoft Network Monitor to see them.

The link posted by multipleinterfaces goes into more detail, but long story short, on a Windows Vista or Windows 7 machine, Wireshark cannot capture packets in monitor mode, which was apparently what I needed to do.
