SYMPTOMS
When you use a program that calls the Web Distributed Authoring and Versioning (WebDAV) GET method on a message that is stored on an Exchange 2000 computer, you may find that the performance of the computer may temporarily decrease. If you create a counter log in Performance Logs and Alerts to monitor the PhysicalDisk object, a spike occurs in the Avg.Disk Write Queue Length counter.
CAUSE
This problem may occur in situations when the message contains a large attachment. For example, this problem may occur if the message contains an attachment that is 15 megabytes (MB). When the WebDAV GET method is called for a message, a temporary file is created for the message in the %SysemRoot%\Temp folder on the computer. When the size of the message (including the attachment) is large, performance may temporarily decrease during the time that it takes for the computer to process the request.
