Same error

[SqlJunkies User]

I have pretty same problem with XmlDocument.Loa d(). It seems to appear after KB834623 hotfix installed. Here is the information to reproduce error:

Technical info:
• Windows XP Professional SP1
• .NET Framework 1.1
• KB834623 hotfix for .NET Framework 1.1 installed (installing with .NET Speech SDK 1.0)

Steps to reproduce:
1. Create new ASP.NET web application in IIS, for example, XmlDocBugTest
2. Place test XML document in the root of application. Example - test.xml:

<?xml version="1.0" encoding="utf-8" ?>
<test>
123
</test>

3. Place button on any web form (for example, WebForm1.aspx)
4. Place following code for button OnClick handler:

using System.Xml;

//...

private void Button1_Click(o bject sender, System.EventArg s e)
{
XmlUrlResolver resolver = new XmlUrlResolver( );
resolver.Creden tials = System.Net.Cred entialCache.Def aultCredentials ;
XmlTextReader reader = new XmlTextReader(" http://localhost/XmlDocBugTest/test.xml");
XmlDocument doc = new XmlDocument();
doc.XmlResolver = resolver;
doc.Load(reader );
}

5. Load web page and click on button. You will achieve following error:

Note: it seems to appear only if you access XML file located on your local machine thru the HTTP protocol (in XmlDownloadMana ger.GetNoneFile Stream() method).

PS: Not only me receive problems with this hotfix. Reference: http://www.mcse.ms/message719906.html
