ID: Q180718

The information in this article applies to:

Microsoft Windows NT Server version 4.0

SYMPTOMS

Dismounting a Macintosh volume while Macintosh clients are still connected to that volume may result in a stop screen if the administrator immediately attempts to disconnect those sessions through the Users option of the Macfile application in Control Panel.

When the remote client is in the process of disconnecting and the administrator also starts disconnecting, there is an extremely small timing window where this memory may get freed twice.
