SYMPTOMS
Your computer running Windows NT 4.0 Service Pack 3 (SP3) that is configured as a domain controller may stop responding (hang) when approximately 400 users with a centralized desktop scheme are connected to the domain controller.
CAUSE
With this centralized desktop scheme, the most significant network load came about when the Start Menu and Desktop were refreshed. The Explorer shell from the client causes a series of NotifyChangeDirectoryFile calls to be made to the file system of the server during these refresh cycles. Each call causes a notify sync object to be allocated and places an IRP in the notify queue.
In this configuration, the 400 users generated a significant number of notify syncs, which eventually would create a mismatch between an associated IRP and its notify synch object because of a timing issue.
RESOLUTION
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
