SYMPTOMS
Consider the following scenario. You use Microsoft Internet Explorer 6 on a Microsoft Windows XP Service Pack 2 (SP2)-based computer. You try to connect to a Web site after you configure autoproxy detection in Internet Explorer. In this scenario, the Internet Explorer program stops responding.



CAUSE
This problem occurs because of a code defect in the Wininet.dll file. This code defect creates a condition where the Wininet.dll file waits indefinitely for a pending request in the code of the DLL to finish. This request is never processed, and this prevents Internet Explorer from opening the requested Web site.
