You were not connected because a duplicate name exists on the network.

Posted By:      Posted Date: September 07, 2010    Points: 0   Category :ASP.Net
I'm trying to utilize Active Directory user authentication in an ASP.NET web page and keep getting the above error when trying to authenticate. I'm not trying to connect to the network. My connecting string for the application, and membership code from web.config are listed below.  Most of what I've read on this error deals with actually connecting a machine to the network. I'm really only interested in authenticating the user. <connectionStrings>    <add name="ADConnectionString" connectionString="LDAP://dc.<mydomain>.edu/DC=<mydomain>,DC=edu"/></connectionStrings> <membership defaultProvider="MyADMembershipProvider">    <providers>        <add name="MyADMembershipProvider"            type="System.Web.Security.ActiveDirectoryMembershipProvider"            connectionStringName="ADConnectionString"         />    </providers></membership> Any help would be appreciated.

Intermittant error: "A connection attempt failed because the connected party did not properly respon



I'm having a doozy of a problem, and can't find a solution.  I have a WFC Web Service installed to a pair of servers, and accessed through a load balancer.  I am accessing the service from an ASP.NET client app, also via WCF.  The Client is not load balanced.

I'm getting an intermittant error:

(Inner Most Exception) System.Net.Sockets.SocketException:  A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond x.x.x.x:80

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.

Checking if a URL Exists


I've got a HttpHandler which outputs XML to the client to play video, it outputs the url to the video, video name etc... Validates the request etc.

However sometimes when i upload new video the main URL doesn't pickup the file from the CDN so i have to use a different URL to go directly to one of the main servers.

For example the CDN url is:
One of the server urls is:

What i want to do is check to see if the file can be reached off the .net url before posting it back to the user.


if http://videos.****.net/ar/ar_1003_scene_1.ext response then
> post http://videos.****.net/ar/ar_1003_scene_1.ext to client
> post http://videos1.****.com/ar/ar_1003_scene_1.ext to client

I hope that makes sense.

I thought of doing a WebRequest/WebResponse but i don't want the file to come back, i just wanna know if its there or not. My site is on a single server while all the video is on a CDN.

(i can't post the url because it's NSFW)

Duplicate column names from forms in SharePoint lists



I'm in the process of migrating from a WSS 2 site to WSS 3/MOSS. On the old site I used an Infopath 2003 form for absence requests. During the migration I now use Infopath 2007. There wasn't any problem initially when the form was stored with the SharePoint form library. However, when I published the form as a content type from Infopath 2007 and then added that content type to the form library, there are two columns for each piece of data from the form. (One from the content type and one from the form list.) I relinked each old form (list content type) to the new AbsenceRequest content type and removed the original one from the list. However, the duplicate column names are still there. Since they came from the Infopath form, they are not editable or deletable from the SharePoint list management interface. The duplicate column names make it tough to build views since it isn't apparent which column to use in the form building UI. It can be determined form the overview display, but it is very cumbersome.


Does anyone know a way to get rid of the old, absolute, columns?

need help about HttpWebRequest : A connection attempt failed because the connected party did not pro



I am creating an application for bulk mailing. Its on my subdomain. 

The functionality i require here is I need to copy an html file located in different subdomains on my production server to my bulk mailing application. 

I am using HttpWebRequest for the purpose where I take the url of the page into a text box and create a HttpWebrRequest. 

The code is as simple as follows.

HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://mydomainorsubdomain.com/dir1/page.html");

and this is working fine on my local development environment that is in VS2010 

but when i put code to production server it is throwing following error.

>>>Check duplicate while inserting record from Texbox.

Hi, On inserting record, I want to check that for example if a user enters a telephone number for any record is already in the database then it should validate that the number already exists in table and you cannot enter a duplicate value. Then if user will provide some other telephone number then he allows to insert record. For insertion of record I used ObjectdataSource. User will enter telephone number in a simple textbox. I may want to inform that I am working in asp.net2.0 and also not allowed to use any third party control or ajaxtoolkit. Any idea would be appreciated.
