This article was previously published under Q314122



SYMPTOMS
When you submit a client request to the Web Requests listener on an Internet Security and Acceleration (ISA) Server 2000-based computer, an access violation occurs in the ISA Server2000 Web proxy service.



CAUSE
This problem may occur if both of the following conditions exist:
 * The Web request requires renegotiation. For example, by using client certificate authentication.
 * The Web request contains a body.

ISA Server 2000 incorrectly considers the request body as the beginning of the renegotiation packet and enters the wrong state. This causes an access violation in the Proxy_Request function.



RESOLUTION
To resolve this problem, install Service Pack 1 (SP1) for ISA Server 2000. To obtain ISA Server 2000 SP1, visit the following Microsoft Web site:

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
