If you use a dial-up connection to connect to the Internet, you may be prompted to make a connection when you run a multimedia program. However, you may not be able to make the connection.
This problem occurs because the network is overloaded by multicast packets that have a Time-To-Live (TTL) setting of 0 (zero). The TCP/IP stack does not handle IP multicast packets correctly and transmits the last fragment of each multicast packet on the network. Therefore, the multicast packets overload the network.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
Multicast packets that have a TTL setting of 0 should not be transmitted on the network. Such multicast packets should only be looped back to other programs in the local computer.
Before you install the Microsoft Windows 98 hotfix or the Microsoft Windows 98 Second Edition hotfix, you must first install the Dial-Up Networking 1.4 upgrade.
