This is driving the whole team crazy. There must be some simple mis-configured part of IIS or our Web Server, but every time we try to run out ASP.NET Web
Application on IIS 7.5 we get the following
error...
Here's the
error in full:
HTTP
Error 500.19 - Internal Server
Error
The requested page cannot be accessed because the related configuration
data for the page is invalid.

The machine is running Windows Server 2008 R2. We're developing our Web
Application using Visual Studio 2008.
According to Microsoft the code 8007000d means there's a syntax
error in our web.config -- except the project builds and runs fine locally. Looking at the web.config in XML Notepad doesn't bring up any syntax errors, either. I'm assuming it must be some sort of poor configuration on my part...?
Does anyone know where I might find further information about the error? Nothing is showing in EventViewer, either :(
Not sure what else would be helpful to mention...
Assistance is greatly appreciated. Thanks!
UPDATES! - POSTED WEB.CONFIG BELOW
Ok, since I posted the original question above, I've tracked down the precise lines in the web.config that were causing the
error.
Here are the lines (they appear between <System.webServer> tags)...
<httpHandlers>
<remove verb="*" path="*.asmx"/>
<add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/>
</httpHandlers>
Note: If I delete the lines between the <httpHandlers> I STILL get the
error. I literally have to delete <httpHandlers> (and the lines inbetween) to stop getting the above
error.
Once I've done this I get a new 500.19
error, however. Thankfully, this time IIS actually tells me which bit of the web.config is causing a problem...
<handlers>
<remove name="WebServiceHandlerFactory-Integrated"/>
<add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory,System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/>
<add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/>
<add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/>
</handlers>
Looking at these lines it's clear the problem has migrated further within the same <system.webServer> tag to the <handlers> tag.
The new
error is also more explicit and specifically complains that it doesn't recognize the attribute "validate" (as seen on the third line above). Removing this attribute then makes it complain that the same line doesn't have the required "name" attribute. Adding this attribute then brings up ASP.NET
error...
Could not load file or assembly
'System.web.Extensions,
Version=1.0.61025.0, Culture=neutral,
PublicKeyToken=f2cb5667dc123a56' or
one of its dependencies. The system
cannot find the file specified.
Obviously I think these new errors have just arisen from me deleting the <httpHandlers> tags in the first place -- they're obviously needed by the
application -- so the question remains: Why would these tags kick up an
error in IIS in the first place???
Do I need to install something to IIS to make it work with them?
Thanks again for any help.
