FIX: ASP.NET requests run, but no ASPNET_WP.EXE worker process appears in Task Manager (840870)


The information in this article applies to:

  • Microsoft .NET Framework 1.0

SYMPTOMS

If your Machine.config file contains syntax errors in the proxy bypass list, the wrong process model may be used to run ASP.NET requests. For example, if you add the following code in the <system.net> section of your Machine.config file, ASP.NET requests run, but no ASPNET_WP.EXE worker process appears in Task Manager. 
<defaultProxy>
<proxy usesystemdefault="false" proxyaddress="intranetproxy" bypassonlocal="true" />
  <bypasslist>
    <add address=".*\.corp\.microsoft\.com\:.*" />
  </bypasslist>
</defaultProxy>

CAUSE

This problem occurs because the .config file parser ignores the enable="true" attribute of the processModel element when the bypass list contains an error. (In the example in the "Symptoms" section, a backslash (\) character appears after ".com" in the code.)

The .config file parser then uses the default process model. The default process model does not use a worker process. Instead, ASP.NET requests are served from the Inetinfo.exe process.

RESOLUTION

This software update makes the following changes:
  • The default process model now uses a worker process.
  • The enable attribute of the processModel element is respected, regardless of whether the bypass list contains errors.

WORKAROUND

Correct the syntax error in your bypass list. However, if you omit the enable attribute of the processModel element, ASP.NET will assume that the enable attribute has a value of false unless you apply this software update.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
