Has anyone seem a problem with reading multicast on a Windows server 2008 R2 machine? We're running it on a Dell server PER710 using Xeon CPU's x5678 @ 3.60 GHz with a 64-bit OS. Using wireshark I see that when the router/switch sends out a general request every 125 seconds, the server doesn't always re-request for all the groups it's currently joined to. If there are no other recipients on the same lan joined to the same groups, I would think the server would need to always re-request for the full set of multicast groups it's joined.

これは Windows のバグですか? ファームウェアのアップグレードで修正されましたか?

同じネットワーク内に、同じグループのメンバーでもある別のホストがある場合、そのホストは既に応答している可能性があります。この場合、タイマーが長いホストは応答を抑制します。RFC 2236を参照してください。
