AjaxToolkit's CascadingDropDown control is throwing Method Error 404 in Hybrid system environment (

Hi Experts, We have an Asp.net web application, which is deployed in shared hosting environment. On shared hosting environment initial request to this web application is handled by Linux server and then based on the requested page the Linux server is redirecting request to web server on windows OS. Now, in our web application, we have used ajaxToolkit's CascadingDropDown control to populate three levels of categories. In the hybrid system described above, the CascadingDropDown control is throwing Method Error 404. I would appreciate if some body can guide on how to resolve this issue. The sample of code snap shot is mentioned below. ********************************************************************* Aspx file. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ <asp:DropDownList ID="ddlMajorLevelCategory" runat="server" Width="250px" ToolTip="Select Major Level Category" TabIndex="1"                            SkinID="h6BlueArial"> </asp:DropDownList>   <ajaxToolkit:CascadingDropDown ID="ccMajorCategory" runat="server" TargetControlID="ddlMajorLevelCategory" Category="M" PromptText=&qu

Adding AJAX-enabled WCF Service to the Solution throws an error

Getting "A domain group is missing for one or more services" error when adding new node to existing


Hey all,

Current configuration:

2-node sql 2005 cluster

windows 2003 enterprise R2 w/ sp2 x64

sql 2005 enterprise x64 SP3


In the process of adding a third node into the existing 2-node cluster, we received the

"A domain group is missing for one or more services.  To install SQL 2005 as a failover cluster, domain groups must be specified for all the clustered services bing installed. To proceed, enter the missiong domain group information." 

The existing cluster functions properly and has been running w/o problems for a long while now.  An AD Global Group was created to support the cluster back when the cluster was initially created.


I found different suggestions from people online about this issue, any where from adding registry keys to take trailing blank space from sql resource group name, but none works. 


Any ideas?


Thank you in advance for any assistance.

Jscript error: Object does not support property or method


 Hi, i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work.

I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page.

In my experience, im get this error msg 9 out of 10 times i use javascript in my system.

Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything.

But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error.

Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error.

But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum.

It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work.

So below is my code that i need to use.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>
<script type="text/javascript" src=&quo

AD FS 2.0 in Identity Solutions: Using Active Directory Federation Services 2.0 in Identity Solution


This article explains how you can use Active Directory Federation Services (AD FS) 2.0 to claims-enable Windows Communication Foundation (WCF) services and browser-based applications. The focus is on the token issuance functionality in AD FS 2.0. You'll find out how to use AD FS 2.0 as an identity provider; set up an AD FS 2.0 security token service (STS) to interact with WCF; federate AD FS 2.0 with your custom STS or another AD FS 2.0; enable Web single sign-on and federation with WS-Federation and SAML 2.0 protocols; and externalize authentication logic through Visual Studio. You'll come away appreciating how AD FS 2.0 and Windows Identity Foundation make programming identity solutions in Windows less of a chore.

Web Services: Extend the ASP.NET WebMethod Framework by Adding XML Schema Validation


WebMethods make the development of XML Web Services easier by encapsulating a good deal of functionality, but there is still a lot of underlying XML processing that you have to be responsible for. For example, WebMethods do not validate messages against the implied schema. Because they are not validated, the response that's returned can result in unintended consequences. To address this, the authors extend the WebMethod framework by adding XML Schema validation through a custom SoapExtension class.

SENS: System Event Notification Services and WMI Enable Flexible, Efficient Mobile Network Computing


Networked applications must deal with a host of connection problems ranging from timeouts to congestion to unavailability. If these applications can check the current connection status and, when disconnected, cache transmissions, they become more efficient. Fortunately, both the System Event Notification System (SENS) and Windows Management Instrumentation (WMI) can send notifications to keep applications informed of network status. In this article, the author explains the use of several SENS interfaces, including ISensNetwork and ISensLogon, which trigger events for connects/disconnects and logons/logoffs, respectively. The author then shows how you can subscribe to each of these events, and follows with a discussion of when you might use WMI events instead.
