image not showing (new iis)

[Morten]

hi
I'm in the process of moving a site from a win2003 server to a win2008r2 server.
On my login page I'm using a RadCaptcha image that is now showing a broken link in stead of a captcha image (see src property in code snippet below).
I think it could be a write permissions issue, however, I'm unsure how/where to change what.

Any suggestions?

<telerik:RadCaptcha ID="CaptchaImage" runat="server" ErrorMessage="Entered code as displayed" 
CaptchaTextBoxLabel="" />

<div id="ctl00_cph_cnt_CaptchaImage" class="RadCaptcha RadCaptcha_Default">
    <!-- 2011.2.915.40 --><span id="ctl00_cph_cnt_CaptchaImage_ctl00" style="color:Red;visibility:hidden;">Entered code as displayed</span><div id="ctl00_cph_cnt_CaptchaImage_SpamProtectorPanel">
        <img id="ctl00_cph_cnt_CaptchaImage_CaptchaImage" alt="" src="Telerik.Web.UI.WebResource.axd?type=rca&guid=a4dfd827-ddb3-4dd6-b837-01385b3dc115" style="height:50px;width:180px;border-width:0px;display:block;" /><p><input name="ctl00$cph_cnt$CaptchaImage$CaptchaTextBox" type="text" maxlength="5" id="ctl00_cph_cnt_CaptchaImage_CaptchaTextBox" title="" /><label for="ctl00_cph_cnt_CaptchaImage_CaptchaTextBox" id="ctl00_cph_cnt_CaptchaImage_CaptchaTextBoxLabel"></label></p>
    </div><input id="ctl00_cph_cnt_CaptchaImage_ClientState" name="ctl00_cph_cnt_CaptchaImage_ClientState" type="hidden" />
</div>

in my web.config I have:

<httpHandlers>
    <add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI" validate="false"/>
</httpHandlers>

adding:
<location path="Telerik.Web.UI.WebResource.axd">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>

didn't solve the issue

Hi Morten,

Please check the following articles, which contain useful information concerning deployment of the RadControls for ASP.NET AJAX on a production server:
Troubleshooting deployment on the production server
Registering the HttpHandlers on Windows Vista IIS 7 Integrated mode

If the help articles above are not enough to resolve the issue, could you please provide more information about the problem, so that we are able to provide a full support on the matter at hand?

The following questions will help us learn more about the issue, if you can answer them:

• Is your local server environment, a WebGarden or WebFarm?
• If the above is true, have you configured your environment to use out of process Session?
• Have you correctly registered the HttpHandlers that serve the CaptchaImage in your configuration file? Please note that you must register the httpHandler in both <system.web> ------> <httpHandlers>, and <system.webServer> -------> <handlers>. The first one is for earlier versions of IIS, and the second for later.
• Are you using any kind of user authentication and authorization in your application? If yes, please make sure you have allowed access to the RadCaptcha httpHandler, to all users.
• Which version of RadControls for ASP.NET AJAX are you using?
• Please provide a screenshot of how the Captcha looks.
• Open the FireFox browser and enable FireBug. You need to enable the Net monitoring tool. Please load your page and check if the webresources are loaded correctly. If not, they will be displayed in red color. What is the information displayed in the Response string?

All the best,
Slav
