I am new to Vb.net. I am creating an intranet application which needs the windows loginname. I got the login name from System.Net.CredentialCache.DefaultNetworkCredentials. It worked fine in my localhost machine. But the problem is that when I am trying to access the site from Development server it is showing the error:
The request failed with HTTP status 401: Access Denied
But the same code is working fine in Test environment.I don't have any idea why these both environment behaving differently.
I am using windows Integrated authentication and Anonymous access disabled. Please help me to figure out this issue.
Dim consumeWebService As ws-ProfileService
consumeWebService = New ws-ProfileService
consumeWebService.PreAuthenticate = True
consumeWebService.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials
Thanks in advance.
It sounds like an impersonation issue. Have a read here and see if this helps. It's definitely worth the read even if seven years old.

As far as I know I have followed the instructions for setting up the Microsoft Graph sample https://github.com/microsoftgraph/aspnet-snippets-sample, including joining the Microsoft 365 Developer Program. However when I run the sample and attempt to log in with my new Developer Program user I get the following error message:
Authentication error "Value cannot be null. (Parameter 'value')"
The error us being caught in this routine:
options.Events.OnAuthenticationFailed = context => {
var error = WebUtility.UrlEncode(context.Exception.Message);
context.Response
.Redirect($"/Home/ErrorWithMessage?message=Authentication+error&debug={error}");
context.HandleResponse();
return Task.FromResult(0);
};
If I log in with my personal Microsoft account then everything works fine, so I'm guessing this has something to do with my Developer Program account. The error message isn't very helpful and there not stack trace to speak of. I've tried using Fiddler to see if there's any more information but with no luck either. Any ideas about what I might be doing wrong?
Tested and reproduced the issue. You are getting this error because, as you have created application in one tenant and accessing the application with the Developer Program account(another tenant).
The Solution would be provide Provision for the application (service principal creation) Consent the application with the developer Program account(needs to be admin) if you want to use the application in developer tenant and Please below call
https://login.microsoftonline.com/common/oauth2/authorize?response_type=code&client_id=id&redirect_uri=https%3A%2F%2Flocalhost%3A44307%2F&prompt=admin_consent
After looking at the error messages in the output from the Kestrel web server I discovered that the line causing the problem was this one:
identity.AddClaim(new Claim(GraphClaimTypes.TimeZone, user.MailboxSettings.TimeZone));
and it was because the value of user.MailboxSettings.TimeZone was null. Once I set up a TimeZone in my developer account then everything works fine.
I have a ASP.NET Core with Blazor website and I want to deploy it to Arvixe host. The website is very simple and contains only UI elements no database required. I published the website to a local file system and uploaded it using FTP to the Plesk.
When I am visiting the website, I receive this error:
500 - Internal server error. There is a problem with the resource you
are looking for, and it cannot be displayed.
I have tried to run it on the IIS and I received more details:
Configuration The configuration file cannot be read due to
insufficient permissions.
I tried to add IIS_IUSRS to the group and users for web.config but I am not able to find it because I am using a windows 10 connected to active directory.
Besides, I still don't know how to solve this problem at Arvixe. Does anyone know tips might help?
500 internal error is generic issue. Please kindly check the error message on the server and paste it here. Make sure that your provider has installed .net core bundled on their server and here are tutorial about publsih .net core using plesk https://windowswebhostingreview.com/how-to-publish-using-web-deploy-with-plesk-control-panel/. It should be working fine.
You need to give Full Trust permission (Read-Write-Execute) to your application folder and also to Application Pool and also check if the Runtime version supported by Arvixe matches with your Asp.net Core version.
Also enable the logs in web.config file by setting stdoutLogEnabled="true" to get detailed error so that you can investigate more about the error.
We have a test website that uses Persits ASPPDF to build a PDF using the ImportFromUrl method. It works fine on our test domain, but when I use the same code on another domain (and crucially perhaps, a sub-domain) I get the "MSXML2::ServerXMLHTTP Error: The request has timed out." error.
This leads me to think its related to the problem outlined in
https://support.persits.com/show.asp?code=PS080709171
"the calling Active Server Page (ASP) should not send requests to an ASP in the same virtual directory or to another virtual directory in the same pool or process. This can result in poor performance due to thread starvation."
So perhaps the config of the two servers hosting the two sites (test and live) are different - and if so what would that be? - Or you can't run this method on a sub-domain? Any guidance out there please?
I've had the same issue for weeks and finally found out what the problem was. In my case, it was because I had set to True the options that allow the debug of classic ASP code, without which I could not debug using visual studio. Setting those options back to False fixed the issue.
Good morning . For the first time I have written to stackoverflow.
Currently we have a running server. We are using Apache as the web server and WebLogic 10.3.6 as the WAS server.
There is a problem here ... The WAS server has an action that generates a specific error code when accessing it directly. This particular error code is the 902 error code.
When you log in again, you will be given an error code of 902. If you access WAS directly, it will return error code 902.
However, when you access the web server (domain address), it will return a 500 error code instead of 902. Obviously this seems to be a problem with setting up a web server. I do not know where to return the 500 error code instead of the 902 error code.
Do you have any of these in your Apache configuration? I did not set up my own web server but I did not know that someone else was going out.
If you have a similar experience, please help. Thank you.

I am trying to create a WebSocket client through WebSocket4Net with port 4503.However i could see the the WebSocket status only as "Connecting" as it is neither raising any exceptions nor proceeding further.I was able to throw the Exception OnError Event which states that
"An attempt was made to access a socket in a way forbidden by its access permissions"
Am i missing anything?. Any suggestions or link will be much helpful.Thanks in advance.
ws = new WebSocket("ws://localhost:4503/WSServer");
ws.Opened += new EventHandler<EventArgs>(ws_Opened);
ws.Open();
I've been getting this kind of error today with a different type of socket library. This may be an access permissions problem in Silverlight, but on the server side, I found that I had to shut down Visual Studio, and then launch it with admin permissions in order to start up the service. It's going to be something like that. If it is a Silverlight access permissions thing, you will want to try running it out of browser and turning on elevated trust.
