SYMPTOMS
When a computer running Windows 95 or Windows 98 receives a fragmented Internet Group Management Protocol (IGMP) packet, the computer's performance may degrade or the computer may stop responding (hang) and require a reboot to restore functionality.
Computers running Windows NT 4.0 are also affected by this issue, but other system components prevent any performance degradation.
CAUSE
A fragmented IGMP packet may cause the TCP/IP stack to improperly gain access to invalid segments of the computer's memory.
RESOLUTION
This patch is now available on the Windows Update Web site.
NOTE: If Dial-Up Networking Update version 1.3 for Windows 95 is not installed, you will not be able to view this fix.
