NetMeeting 3.01 SP2 Is Available for Some Versions of Windows
The access violation occurs while NetMeeting is processing
a linked list of conference members to update the call roster during a close
operation. NetMeeting "walks off" the end of the linked list and generates an
access violation. This occurs because of a synchronization problem that makes
it possible for another thread to reallocate blocks of memory released by the
roster-list cleanup code before the cleanup code finishes traversing the list.
This makes it impossible to determine the end of the list in the roster-list
cleanup code.
To resolve this problem, obtain the latest service
pack for Windows 2000. For additional information, click the following article
