Web部分错误：（401）未授权

我有一个查询Web服务的小程序，使用XSLT转换结果并将它们显示在jQuery控件中。当我的代码进入一个网络的一部分，并部署它，但我发现了以下错误：Web部分错误：（401）未授权

The remote server returned an error: (401) Unauthorized.

这就是会加载我的XSLT文件中的代码，这是我怀疑的问题是：

XPathDocument xPathDoc; 
XsltArgumentList args; 

protected override void OnPreRender(EventArgs e) 
{ 
    xPathDoc = QueryRunner.GetQueryResults(); 
    args = QueryRunner.GetColumnsToShow(); 
} 

public static XPathDocument GetQueryResults() 
{ 
    OpacAccess.OpacAccess proxy = new OpacAccess.OpacAccess(); 

    string result = string.Empty; 

    try 
    { 
    result = proxy.query("CompanyName", "username", "password", 
     ReadingList=\"London\"", 1000); 
    } 
    catch (Exception ex) 
    { 
    } 

    // Store the xml of the result 
    XPathDocument xPathDoc = new XPathDocument(new StringReader(result)); 

    return xPathDoc; 
} 

protected override void RenderContents(HtmlTextWriter output) 
{ 
    XslTransform xslt = new XslTransform(); 

    // Load the xslt file and perform the transformation 
    xslt.Load("http://rginfonet/Style%20Library/XSL%20Style%20Sheets/Liberty.xslt"); 
    xslt.Transform(xPathDoc, args, output, null); 
    output.Flush(); 
}

这里是我的堆栈跟踪，如果它是在所有有用的人：
