SYMPTOMS
When you call the Read method from an XmlTextReader class by using the following code: String m_XmlDocument = &quot;http://localhost/bug/file.xml&quot;; XmlTextReader reader = new XmlTextReader (m_XmlDocument); reader.Read; you receive the following System.ArgumentOutOfRangeException error message:

System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Parameter name: The specified value must be greater than 0.

at System.Net.ServicePoint.set_ConnectionLimit(Int32 value)

at System.Xml.XmlDownloadManager.GetNonFileStream(Uri uri, ICredentials credentials)

at System.Xml.XmlDownloadManager.GetStream(Uri uri, ICredentials credentials)

at System.Xml.XmlUrlResolver.GetEntity(Uri absoluteUri, String role, Type ofObjectToReturn)

at System.Xml.XmlTextReader.CreateScanner at System.Xml.XmlTextReader.Init at System.Xml.XmlTextReader.Read

at ASP.t_aspx.__Render__control1(HtmlTextWriter __output, Control parameterContainer)

Note This hotfix cannot be applied on a system that is running the Microsoft .NET Framework 1.1 Service Pack 1.

CAUSE
This exception was a regression from an earlier fix to the XMLDownloadManager class. The problem is caused by the limitation on connections to http://localhost. The default connection limit for http://localhost has changed from 2 to Int32.MaxValue (2,147,483,647). When the XmlDownloadManager class increments the value, the exception occurs.
