Important This article contains information that shows you how to help lower security settings or how to turn off security features on a computer. You can make these changes to work around a specific problem. Before you make these changes, we recommend that you evaluate the risks that are associated with implementing this workaround in your particular environment. If you implement this workaround, take any appropriate additional steps to help protect your system.



SYMPTOMS
When you try to run an application that uses the System.Xml.dll file in the Microsoft .NET Framework 1.1 Service Pack 1 (SP1), the application may experience security permission related errors. When this problem occurs, you may receive an error message that is similar to the following:

System.Configuration.ConfigurationException: Error loading XML file c:\winnt\microsoft.net\framework\v1.1.4322\Config\machine.config Request for the permission of type System.Security.Permissions.SecurityPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed. (c:\winnt\microsoft.net\framework\v1.1.4322\Config\machine.config)

However, if you turn off code access security by using the Code Access Security Policy tool (Caspol.exe), this problem does not occur.



Hotfix information
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next .NET Framework 1.1 service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the hotfix. For a complete list of Microsoft Product Support Services telephone numbers and information about support costs, visit the following Microsoft Web site:

The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

Prerequisites
To apply this hotfix, you must have the .NET Framework 1.1 SP1 installed on the computer.

Restart requirement
You must restart the computer after you apply this hotfix.

Hotfix replacement information

WORKAROUND
Warning This workaround may make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.

To work around this problem, you can temporarily turn off code access security. To do this, use either the Microsoft .NET Framework Configuration tool (Mscorcfg.msc) or the Code Access Security Policy tool (Caspol.exe).

Note To turn off code access security, use the following command:

caspol -s off



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
