• The Macintosh client has a connection to the computer running Windows NT Server (no files open) and the server is restarted, or the Macintosh client is restarted.
• When the network connection between the Macintosh client and the computer running Windows NT Server is broken because of possible network problems.
• The Macintosh client receives a system error, such as a Type 1 or Type 11 error, which forces the client to restart.
WORKAROUND:
To avoid this problem, make sure you close all files and connections to the computer running Windows NT Server before you shutdown your Macintosh client.
