Latest revision as of 17:09, 19 July 2020
Article ID: 254142
Article Last Modified on 11/21/2006
APPLIES TO
- Microsoft Internet Information Server 4.0
- Microsoft Internet Information Services 5.0
This article was previously published under Q254142
SYMPTOMS
When you send a large escape sequence to a computer running Internet Information Server 4.0 or Internet Information Services 5.0, the computer may use 100 percent CPU while it is processing the request. During this time, the server may not respond to other requests.
CAUSE
This problem occurs because the Str::unescape function parses the escape characters in the request string by processing one character at a time, shifting the data over each time, and then starting again from the beginning of the request string. This takes a considerable amount of CPU usage, and can cause the server to stop processing other requests.
RESOLUTION
Internet Information Services 5.0 (Windows 2000)
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
