Hotfix information

Important Two types of packages will be available for this hotfix, a Microsoft Windows Installer (.msi) package, and an Optional Component Manager (OCM) package. If you use Windows Server 2003, you must specify that you require the Windows 2003 (OCM) patch. If you use an operating system different from Windows 2003, you must continue to use the Windows Installer package. For Windows 2003 Server, Windows File Protection monitors the .NET Framework 1.1 files.

To correctly install the hotfix on Windows Server 2003, you must install the OCM hotfix package. If you try to install the Windows Installer package on Windows Server 2003, you receive the following error message:
The installer cannot install the upgrade patch because the program being upgraded may be missing or the upgrade patch updates a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch.
The following error is generated:

The following is a brief summary of the fixes that are included in this package:
  • When the following conditions exist, you may receive a client-side script error in Microsoft Internet Explorer or in a Netscape browser:
    1. You add the following form to a user control:
      <form id="Form1" name="Form1" runat="server">
    2. You add the user control, for example, Workspace1, to a page. When you do this, an auto-generated script that is similar to the following script is added to the page:
      <form name="Workspace1:Form1" method="post" action="formtest2.aspx" id="Workspace1_Form1">
    The script error occurs because the form name and the form ID are different, and the form name contains a colon as a delimiter.

    Another example of the problem in the automatically generated script for a __doPostBack function is the following:
    function __doPostBack(eventTarget, eventArgument){	var theform;	if (window.navigator.appName.toLowerCase().indexOf("netscape") > -1)	{		theform = document.forms["_ctl14:Form1"];	}	else	{		theform = document._ctl14:Form1;	}	theform.__EVENTTARGET.value = eventTarget.split("$").join(":");	theform.__EVENTARGUMENT.value = eventArgument;	theform.submit();}
    Notice that the form has a uniqueID property that contains a colon in the following lines:
    theform = document.forms["_ctl14:Form1"];theform = document._ctl14:Form1;
  • You cannot load multiple ASP.NET worker processes.

    In Microsoft Internet Information Services 5.0 (IIS 5.0), you can configure the virtual directory to run in highly isolated mode (such as in a separate Dllhost.exe). However, ASP.NET ignores the IIS 5.0 settings. Application Domain isolation provides some level of isolation. There are major issues in supporting extensive earlier code. Because the DLLs are loaded in the Domain-neutral space, and all ASP.NET applications run in the same process, an application that contains coding errors or an application that contains malicious code can easily cause the ASP.NET worker process to fail. If this problem occurs, all the hosted applications fail.
  • Client-side data validation in Microsoft Internet Explorer for Macintosh does not work as expected.
  • When ASP.NET tries to unload the AppDomain under high load, one of the CPUs can experience 100 percent CPU utilization.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in the .NET Framework 1.1 Service Pack 1.
