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.
