Runtime error after hosting the website

hello

i have developed a website it's works properly in my own pc but after hosting it it gives error in inquiry module.whenever inquiry send it gives error as shown below


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.

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 -->

<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>

That is a standard error message. Please show us your code and give details as to when this error occurs. At this starge, it can be anything, like martians attacking your PC for instance... ;)

i am using SQL server 2008 as back end and MS visual stdio 2010

I suspect that the server this is now running on has been firewalled, and possibly cannot connect through to Gmail server..

Try using telnet to test if the server can connect to gmail..

on the Server or Via RDP .. start telnet and enter
open smtp.gmail.com 587
and you should get a reply like this ..
220 mx.google.com ESMTP
If not you found the problem...

can you tell me how to start telnet? n do all the things that you have said... and firewall would be off only for gmail? if i change yahoo then it will be done?

Start > Run > Telnet

It's a console app (Old dos text layout)...

Hi CSharpque

I guess you are reviewing your web project from a client pc.

if you want to see detailed error message I suggest you have to go to web server and review for error message from there. it has to give you some idea clear. which is possible issue.


now if your web app is going to send email from server web you'd have to see performance there.

best regards

sir i have write "telnet" in Run but it's can't find.....error occur "Windows can not find telnet. Make sure you typed name correctly and then try again".

actually hosting done by someone else
