Custom Errors in my Website - asp.net

When I am Connecting a website through remote machine, The Website showing the run-time error
Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.
But i want to display entire site in my website, and one more thing i am using Ajax controls in website, they are CalenderExtender control.
Only Ajax Control tabs showing errors, remaining will be executed perfectly.
enter code here
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>

You seem to have an exception somewhere, it may (or may not) be related to your configuration of the AJAX controls, and you need to correct this first. Check the event log on the server to see the exception details, or just configure your site to expose the details in the browser (which is suggested in the error message you're currently seeing.
You should have only a single <customErrors> tag in your web.config:
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
Set the mode to "off" if you want the site to display all the exception details. However, on production websites, it's generally recommended never to display these details to users.

Web Application Web Config run time error

Im working with Visual Studio 2012 Web Forms the website is starting normally when i open it from local server but when i move the files to GoDaddy hosting into httpdocs this error appears
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->

<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>
Your code is throwing an exception that you can't see. Change your code to mode="Off" as the message indicates. Long term I would recommend using a logging tool like ELMAH so you can see the exceptions and give end users the friendly page. http://www.hanselman.com/blog/ELMAHErrorLoggingModulesAndHandlersForASPNETAndMVCToo.aspx

customError on web.config-originated Server Error

NOTE
I've determined the the problem I'm describing below is specific to an error enountered loading DLL files specified in the web.config file. I would like to present a user-friendly error even in the case of web.config errors.
END NOTE
When my ASP.Net application encounters a server error I would like it to present a custom error message to the user instead of the following default scary message.
Server Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>
I wrote a very simple HTML page and put it in the root of my application. It is called MaintenancePage.htm.
I've set my web.config file to the following:
<customErrors mode="RemoteOnly" defaultRedirect="MaintenancePage.htm">
<error statusCode="404" redirect="PageNotFound.aspx" />
</customErrors>
I've also tried ~/MaintenancePage.htm and http://[mysite]/MaintenancePage.htm. None of those options seem to work.
The way I'm testing this is to rename a DLL my project depends upon and then loading up the site in a web browser. I would expect that since there is an error and a defaultRedirect set there should be no problem showing the error page, however, I'm obviously wrong.
I've search around concerning this problem and it seem that most people are trying to redirect to an aspx page, and are encountering error with doing that. Many even report that they can't get the aspx page to load as a defaultRedirect, but they can get an html page to load.
What could I be doing wrong here?
I should note that I'm doing my testing from a different network outside the company firewall, so changing RemoteOnly to On is not the issue per the documentation. In testing changing RemoteOnly to On had no effect, as expected.
Change RemoteOnly to On.
RemoteOnly:
Specifies that custom errors are shown only to remote clients and
ASP.NET errors are shown to the local host
Also, your URL may be absolute or relative.
Read more about the customErrors settings
To watch it work locally:
<customErrors mode="On" defaultRedirect="/MaintenancePage.htm">
<error statusCode="404" redirect="/PageNotFound.aspx" />
</customErrors>
Easier way to test.
Try a bad url and watch your 404 error take over
Put this on your default.aspx page <% throw new Exception("gaah"); %>
And one other thing to consider: Error Logging. Can be achieved easily through ELMAH.

HTML & ASPX Link Issue

I've recentley moved my entire website from the root directory into a secure folder, but when I try to access it I now get a error: Runtime Error - Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>
Does anyone know what I'm doing wrong?
Set it to off to view the error (only if it's on a staging, non-production server). Remove the custom error page to see what's going on. Try and re-create the error on your dev machine first. You also have the option of logging or emailing the error stack to yourself.
Instead of moving the entire site to a "secure folder", implement some form of authentication for the pages you wish to protect.

Server Error in '/domain/website' Application

I am getting following error while i deployed the website..
Server Error in '/domain/website' Application.

</system.web>
</configuration>
I tried changing customErrors mode="Off" But no Joy ..same error repeats ...
Moreover , GenericErrorPage.htm is missing is this causing the error?
Any helping hands?
This is possibly because there is a syntax error in web.config. You could try replacing your current web.config with one that only contains this and see what happens:
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
Are you using dual web.config in your website. eg.
if you are using one web.config in /domain and another in /domain/website. You need to convert the /website as an application.
however, I would suggest you to log into the server and browse the page, you will be able to see the real issue. If you are unsure how to fix it. post it once. We might be able to help you.
