IIS HTTP Error 500.19, Error Code 0x8007000d

I probably come across this error at least once per year. Ran into it again today when setting up a website to host locally in IIS, on a computer I don't use much.

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    Unknown
Handler    Not yet determined
Error Code    0x8007000d

Config Source:
   -1:
    0:


Microsoft's documentation for that error code helpfully points out:

"This problem occurs because the ApplicationHost.config file or the Web.config file contains a malformed XML element."

Well that clears it up. Just remove the malformed XML element on line 0...

Except that the site runs just fine on other systems, and even in IIS Express on the same machine that's causing the error, so clearly there's no "malformed XML".  Anyway, it turns out that if your web.config has a section for something like IIS' URL Rewrite module, but you don't have it installed, IIS will get so mad that all you'll deserve is the silent scorn of an empty error message.

In my case, the solution was to install the URL Rewrite module via the web platform installer.

Using Log4Net to use both event log and a rolling log file

Here's the config section, note that the applicationNameproperty in the EventLogAppender needs to be the same as the event source in the windows event log that you want to log to.  If the event source doesn't exist, that appender won't work.  In this particular project I create that during install using WiX (which is covered in another post)

  <log4netdebug="true">

Using WiX to create an event source during install of a .NET framework project

Edit: so I guess I wasn't the only one confused with this stuff, as it's been my most popular post by far!  If I've helped you out or saved you some time, please let me know in the comments :)

In order for this to work, you have to add references to WixUtilExtension and WixNetFxExtension to your WiX project.  Once that's done, add this inside a <Component> element:

<Util:EventSourcexmlns:Util="http://schemas.microsoft.com/wix/UtilExtension"Name="EVENTSOURCEGOESHERE"Log="Application"EventMessageFile="[NETFRAMEWORK40FULLINSTALLROOTDIR]EventLogMessages.dll" />
Obviously replace EVENTSOURCEGOESHERE with your event source name.  NETFRAMEWORK40FULLINSTALLROOTDIR is a property set by the WixNetFxExtension which stores the path to the .NET framework v4 directory, but you can replace this with the corresponding property for the directory containing the relevant EventLogMessages.dll file.  So if you're using the .NET framewo…

How to make yourself a Dynamics CRM 2011 Deployment Administrator

Today I needed to deactivate one of our Dynamics organisations, but when I opened the Dynamics Deployment Manager, I received the following error:

"Only the Deployment Administrators are able to use Deployment Manager. You are not a Deployment Administrator."
Bummer. I did a bit of Googling and found this post by Ronald Lemmen (thanks for pointing me in the right direction!).  Since the Dynamics Deployment Manager is obviously checking the MSCRM_CONFIG database for this information I attached a database trace to it and found that it's executing these queries (among many others):

exec sp_executesql N'SELECT  Id, [DefaultOrganizationId], [IsDisabled], [Name]   FROM [SystemUser]   WHERE ((([Name] = @Name0)) ) AND (IsDeleted = 0) ', N'@Name0 nvarchar(41)',@Name0=N'{My windows domain account}'
