DOCUMENT:Q155058 15-MAR-2000 [iis] TITLE :IIS May Stop Responding after Processing Several Client Queries PRODUCT :Internet Information Server PROD/VER:winnt:1.0,1.0c OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Internet Information Server versions 1.0, 1.0c ------------------------------------------------------------------------------- SYMPTOMS ======== Internet Information Server (IIS) may stop responding after processing several Universal Resource Locator (URL) requests for an .htm file with additional relational operators as in the following example: http://www.server.com/default.htm/...and so on... CAUSE ===== IIS enters an infinite loop trying to service URL requests for .htm files with additional relational operators. This behavior would eventually result in several server pool threads in infinite loops taking CPU cycles and causing IIS to stop responding. STATUS ====== Microsoft has confirmed this to be a problem in IIS versions 1.0 and 1.0c. This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces): S E R V P A C K Additional query words: prodiis ====================================================================== Keywords : kbnetwork Technology : kbiisSearch kbiis100 Version : winnt:1.0,1.0c ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
