HTTP 500 or HTTP 403 error when requests are sent to Exchange 2000 Server (327124)


The information in this article applies to:

  • Microsoft Exchange 2000 Server
This article was previously published under Q327124

SYMPTOMS

When a request is sent to Exchange 2000, you may experience any of the following symptoms:
  • If a request is sent for .asp items that are located on the Exchange 2000 server, you receive an HTTP 500 error.
  • When a request is sent for Exwform.dll Internet Server Application Programming Interface (ISAPI)-rendered requests, you receive an HTTP 403 "forbidden" error.
  • You may receive a message that says you have received an HTTP 500 error.
  • You may receive an error message that is similar to the following error message:
    The operation has failed.

CAUSE

This problem occurs because the URL handling code is allocated memory off the stack. Each thread is given a fixed stack size to work with. If the stack size is exceeded, an exception occurs that causes the operation to fail.
