Q248663: Booting Node may Prevent Running Node from Accessing Quorum Disk

SYMPTOMS
========

If the network connection between cluster nodes does not function properly on
Windows NT 4.0-based computers that are configured as part of a cluster with a
quorum disk, a cluster node that is starting can prevent a node that is
currently running from gaining access to the quorum disk. This may cause the
cluster on the running node to stop and all processing to be moved to the second
node.

During Windows NT 4.0 arbitration when a communication loss occurs, drives owned
by the non-quorum owner may not have their cache flushed during arbitration.
