While running an app from the server where it is deployed the website works fine, however when trying to access it from a different machine(placed in same network), using the same credentials, it shows that I am not an authenticated user.

I'm having trouble with accessing my webservice.
I've got a webapplication and inside this webapplication I have a webservice. An external program is going to use this webservice in the future, but for now that is not the problem. this webservice is also called from inside the webapplication. this is where the problem starts.
I keep getting this error:
The remote server returned an error: (401) Unauthorized.
I tried with imporsonate= true, but it didn't work

the webservice is called like this:

I hope some one can point me into the right direction.

I'm trying to use ASP.NET WCF Authentication Service from a Winforms Application.
I am referring to this article as a tutorial.
for silverlight clients, the WCF Auth service works well.
but for Winforms Apps,
[Code]....the AuthenticationServiceClient.IsLoggedIn() always returns false even after login.
what is the cause of this and is there another approach I should take when I leverage ASP.NET authentication from Winforms?
We have a web application that makes a call to a remotely hosted ASMX service that worked in Server 2003 under IIS6. We are now migrating it to a Server 2008/IIS 7 setup and it doesn't appear that the application makes the call to the remote web service anymore. We ran Wireshark and don't see any traffic to the service URL. It seems to throw a 404 error without trying to connect.
Is there some security policy or restriction in Server 2008 or IIS 7 we need to set to allow an ASP.NET application make a call to a remote web service? We are using Network Service as our application pool user, but also tried using Local System as a troubleshooting step. In addition, the same code works if run from a console application on the server instead of the web application.
Is there some setting under IIS7 or server 2008 that would be causing this?
I have installed a web service in a client machine, its accessing a mapped network drive from a remote machine. But when its trying to read files from that file I'm getting this error

A site that utilizes Windows Authentication.It accesses the LOGON_USER variable to pull the domain and user.It works fine in the development environment.It works fine on one of my servers.We are in the process of setting up a new server for this application to be hosted on.When I setup the new server,the LOGON_USER is always empty for remote computers.Windows Auth is turned on.I have tried it with Anonymous Access on (how the current server is setup) and also off.If I remote on to the server and run the application locally,LOGON_USER is filled.When I access the site via IE from a remote machine,it prompts three times and then fails.Even if I key in credentials in the Windows prompt.nothing
View 6 Replieswe would like to redirect the user to a given page if the authentication to our SharePoint site fails (i.e. the standard windows login prompt pops up three times - we are using windows authentication). No matter what option we try it always ends up bringing the user back to a blank page.
We have tried writing a HttpModule (and catch the if Response.StatusCode = 401), which doesn't seem to fire any events if the user is not authenticated. We have tried writing a HttpHandler, but of course we can redirect the user if there is an error code but can't continue onto the desired site if not. We have tried doing the following in the web.config:
<customErrors mode="Off">
<error statusCode="401" redirect="http://social.msdn.microsoft.com"/>
</customErrors>
Which doesn't work, again taking us to a blank page.
I am in the process of designing application in case user authentication if failed i need to redirect to default page (NT Authentication). Is there any way you can redirect the user on IIS if the user is fail go through the NT authenticaiton at IIS level.Options 1 : Always land the user to defalut page and validate there and redirect to site based on the access give the directory level access. I am looking if there any options to let the user to default page in case user access is denied.
View 4 RepliesI created a mixed mode authentication mechanism based on a few of the articles that I have read on this topic. It's similar to something like this: [URL]
Basically, there are two web applications. One accepts the Windows Auth and one accepts Forms Auth. The Windows Auth then creates a forms auth ticket and passes control to the Forms auth application. This solution works fine when both applications are housed within the same IIS web site.
Now, order to control the security of this solution we set up multiple IIS web sites on the same machine. Web Site 1 serves external traffic (forms auth) and Web Site 2 serves internal traffic (windows auth).
So the design is that an internal user can hit the site using Windows auth via a internal name (myserver) while the external users use Forms Auth hitting [URL].
All that said, the solution works when the two applications are in the same site. Doesn't work when they are in different sites.
I am trying to implement a simple role based authorization using forms authentication in ASP.net. It works perfectly fine in my local system but fails when I deploy in production (shared hosting). Whenever I try to log in, rather than taking me to the default page in specified directory it throws me back to the login page. I suspect that there is some issues with the configuration but not sure where the problem is. The code is provided below:
Web.config (root):
[Code]....
Web.config (Member directory):
[Code]....
Login.aspx:
[Code]....
Global.asax:
[Code]....
Works fine in local machine but shared hosting is not taking the authenticated user to the pages inside the secured folders. What can be the issue?
I have a SQL server in my office. I can connect from my home development workstation website to the remote SQL server with no problems but when I upload the site to the web host and try and use the same SQL server it fails with 'A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible'
View 4 RepliesJust to describe the scenario. I have a website. This lives on a webserver. On that webserver is an SQL server. The website connects to this database using windows authentication. I have written a windows form application that connects to the SQL Server on the webserver. This application is being run from a location on out intranet. The Winform application use SQL authentication to connect to the database. The SQL Server didn't have mix mode authentication enabled. So I enabled it. The winform application could now connect to the SQL Server.
This is where it starts getting a little strange.
The Website that was already connecting find using integrated authentication starts failing with:
Login failed for user 'NT AUTHORITYNETWORK SERVICE'
When you are enabling mixed mode authentication, you are adding another authentication method, why would the original Windows authentication fail?
I have problem accessing an SQL server DB on a remote server.Actually, I had no problem with creating a connection string to it using the Visual Web Deveoper 2005 Express Edition GUI, however, I have problem connecting to it through the code.This is the connection string created by the GUI, and connection test on the connection wizzard GUI just works fine.

I'm using VS 2010 RTM and SQL Server 2008 on my clean development laptop, running Windows 7 Pro.
Using Visual Studio's Server Explorer, I can easily do an Add Connection by simply right-clicking, and then completing the dialog, and choosing "Use Windows Authentication". I can then click the button "Test Connection".
However, if I wish to do an Add Connection, and then choose "Use SQL Server Authentication", I get a message "Login failed for user 'appSlir'", as shown here:
When I try the same thing on my other development machine, which is VS 2008, SQL Server 2008, and Windows XP Pro, it works fine.
There seems to be a problem/bug that prevents Add Connection with "Use SQL Server Authentication" to SQL Server 2008, when running on Windows 7 Pro.
writing a web Service and one of its web method, I want it to download a png file in form
of buffer from remote server. And My consume application will write that buffer retured by Web service in to file on User's Computer.
However, I am able to do this using Local Web Service but when I published that service on my web server, I always get null retuned
And even in one of my test code while copying file from that server , I always get Access Denied.
Following things I have done for above issue.
1] I even tried making the Anonymous user for the web service the system administrator (with the correct password), to no avail.
2] I also tried sharing out the folder I'm pulling files from to allow access from Everyone.
[Previously same service was working fine on another remote server with IIS 7.0, we checked server IIS Settings but in vain.]
if you know where we are mistaken guide me to resolve this issue as its very urgent.
I'm still trying to deploy this site, but with every problem I solve, another arises. Anyways - I've set up the database at my hosting to allow remote connections, and it is running Sql Server 2005. On my development machine, I am working with Sql Server 2008.
I've installed the asp.net schema on my hosted database, and have created several users from the ASP.NET web administration interface, as well as tested that the login works. Running the application locally with the remote connection string nets the same results. However - I'm able to run my scripts and generate my tables and stored procedures without errors - but when the site is run I get the following error on all of my .aspx pages that try to access a stored procedure:
Server Error in '/' Application. Incorrect syntax near 'LoadProfileData'. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Incorrect syntax near 'LoadProfileData'.

Line 66: }
Is this a possible Sql 2005 vs 2008 issue? I'm hoping someone else has seen this issue in a similar scenario and can point me in the right direction. The server is running asp.net 2.0, 3.0 and 3.5 and IIS 7.0.
The remote server returned an error: (407) Proxy Authentication Required.I get it when I use the GetReponse() method in WebRequest Dim request As WebRequest = WebRequest.Create(getNextURL()) Dim httpResponse As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)
View 1 RepliesI have a web application (intranet based) which uses Windows Authentication. Unfortunately there are public computers that have public logins at some company locations. My web app doesn't support these public logins because I need to know the user workingSo, even though these public users are windows authentication users, my app will fail because I have no user account setup for that particular account. I want to then try Active Directory Authentication.In my Default.aspx.cs I'd have something like this
protected void Page_Load(object sender, EventArgs e)
{try
userContext = new UserContext(); // If the authenticated user isn't a user in my system then throw an exception

We are using membership provider for LDAP authentication. It is working as it should.
But what all configuration settings I have to do so that
all the future requests to this application run under the security context of the Logged in user account not through the some default user set in IIS.
We need to have this working because all the permissions on the database are based on the logged in user.
We are using form authentication for LDAP authentication. And having impersonation = true in web.config.

View 11 RepliesI am on SBS 2003. Whenever I approach either ipaddress/remote, ipaddress/monitoring or ipaddress/backup I get the error below. When I do ipaddress/Exchange or ipaddress/newvirtualdirectory it works allright. This situation happens when I appraoch that site from a wan, from a lan and local on the server itself. This is the error message I get:
[Code]....
We have an issue with an internal application, where accessing it from LAN (private n/w) works fine, while access from external n/w throws up erratic behavior.
The Current System :
an aspx page (asp version 1.0) hosted on the IIS server (6.1). The front end is a vb form that connects to a sql 2000 database.
Users' credentials authorized using NTLM security.
Access from an external n/w - a reverse proxy configured with an ISA server 2006 to authenticate credentials.
Domain Controller - Windows Server 2008 R2 x64
The issue when accessed from external n/w :
everytime an entry from a drop-down is selected from an Ajax enabled control, instead of the fields populating, the page gets refreshed and the content of the box are cleared.
Also, clicking on other items that normally hyperlink to other pages, results in nothing happening.
Upon investigation, we realized that :
Everytime it fails, a string - "&AuthResend" followed by an alpha numeric string is attached, which attempts to authenticate the user's credentials everytime a request is made to the server.
ISA error logs yielded the following error msg :
"12210 Internet Server API ( ISAPI ) has finished handling the request. Contact your system administrator. "
This behavior is inconsistent except when accessed from Google Chrome, where it fails each time.
We have applied all the recommended hot fixes from Microsoft's KB pages.
I have a simple WCF service that retrieves some data from the DB. When I host the service on local serviceHost everything works fine, but when I host the same service on local IIS (7.5 - windows 7) I get this exception: The Undelying provider failed on open.
I have some logging services inside the service and I found out that this exception occures only when the service calls some DB service (not one particular, any DB service). The strange thing is that when the service is not hosted on IIS this same DB call works fine.
Things I've done: enabled ASP.NET impersonation on the IIS server -> didn't help.
Another thing : I'm using sql server 2008 express.
