On Windows Server 2003 and 2008, you will see one or more warnings when WebFOCUS Visual Discovery Workbench AE is started, if the Internet Explorer Enhanced Security Configuration is in effect for your account. This occurs because the embedded Internet Explorer control is used in the application. The warnings can be dismissed, since pages from Internet sites are not normally displayed in the application. Alternatively, the warnings can be avoided by disabling the Enhanced Security Configuration from the Add/Remove Windows Components or the Server Manager, as described in the following Microsoft article:

If you receive the following error message in a browser while connecting to the WebFOCUS Visual Discovery Server AE:

Server Error in '/ADV' Application and A potentially dangerous request. Cookies value was detected from the client

or the following exception:

System.Web.HttpRequestValidationException

You can eliminate these errors by modifying the web.config file. In the <system.web> section, add the following attribute to the httpRuntime line:

requestValidationMode="2.0"

For example:

<httpRuntime executionTimeout="1200" requestValidationMode="2.0" />
