I've been building a silverlight application and a WCF service for a while now and recently tried to host them in IIS7.

I installed IIS7 on Windows Server 2008 R2 and added these two application to my default website. I am having a number of problems so im hoping one of you can help out...

1) The silverlight and WCF service applications do not work with pass-through authentication. I need to "connect as" the administrator server account when setting up the application. I read online that you should only need to use the "connect as" field when you are connecting to another computer. If i dont supply the admin credentials i get this error. Do i have to set up permissions somewhere else?

HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Detailed Error Information Module IIS Web Core Notification BeginRequest Handler Not yet determined Error Code 0x80070005 Config Error Cannot read configuration file due to insufficient permissions Config File \?\C:\Users\Administrator\Documents\My Dropbox\Research Masters\Project\WCFService\Website\web.config Requested URL http:://localhost:80/WCFService/Service.svc Physical Path C:\Users\Administrator\Documents\My Dropbox\Research Masters\Project\WCFService\Website\Service.svc Logon Method Not yet determined Logon User Not yet determined Config Source -1: 0: Links and More Information This error occurs when there is a problem reading the configuration file for the Web server or Web application. In some cases, the event logs may contain more information about what caused this error.

2) Visual studio generated 2 webpages to run my silverlight application (.html and .aspx). When I am running the silverlight application (connected as admin) I can navigate to the .html page, no problem. When I try to open the .aspx file i get the following error

Server Error in '/Platform' Application.

Access is denied.

Description: An error occurred while accessing the resources required to serve this request. You might not have permission to view the requested resources.

Error message 401.3: You do not have permission to view this directory or page using the credentials you supplied (access denied due to Access Control Lists). Ask the Web server's administrator to give you access to 'C:\Users\Administrator\Documents\My Dropbox\Research Masters\Project\Platform\Website\PlatformTestPage.aspx'.

Version Information: Microsoft .NET Framework Version:4.0.30128; ASP.NET Version:4.0.30128.1

3) The WCF service runs fine (again, connected as admin) until i restart the server. When i try to run the WCF service after a reboot, the mysql assembly seems to be missing from the solution. If i just rebuilt the solution and run the service again... it works (until next restart). Whats causing this error?

This is my first time using IIS7 so this is all new to me at the moment so I have no idea how to set up the server correctly, I'm just learning as I go. The first two seem to be access denied alright. How do I fix this? - Eanna

My suggestions:

1) Check your web application folder's permissions. You should edit the permissions on your web application folder so that the IIS user can read from the folder. So you should open the folder properties dialog for the folder in the windows explorer and check if the application pool user has at least read permissions. If you didn't provide another user for the application pool, then the default user should be IIS_IUSRS.

2) Check if the asp.net is enabled in your system by running:

If you have .Net 4 installed in your system: "%WINDIR%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe" –i Otherwise: "%WINDIR%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe" –i

The above command will register/repair the your .Net installation with the IIS.

3) Is your mysql dll locate in the bin folder? I would check if you also have permissions to read this folder. If the dll is not in the same folder as your application dll, check if the dll is installed in the GAC.

1)Give permissions to the folder for the IIS_IUSRS group. Also see if the application pool for the application in IIS manager->"Application Pools" has the Identity set as "LocalSystem". For me it was "NetworkService", setting it to "LocalSystem" solved it.

You must not be able to host silverlight applications with IIS7. Try hosting your silverlight app on an apache server with a php / html script.
