Every time we reboot our DNN Server, the config files get reset and it causes our websites to throw a 500.19 error reading that you cannot have duplicates of the asp.net filter settings. There are 2 places where these can be set in the ApplicationHost.config and the "ApplicationPoolNameOfYourChoice".config (in my case DNN_Main) under inetpub/temp/apppools folder. So now every time I reboot the server I go into the DNN_Main.config file and remove the extra lines for ASP.Net_4.0_32bit and64bit under the <isapifilters>. I restart IIS and it all works again. It appears DNN includes its own references to the asp.net filters so how can I stop this duplication from resetting each time I reboot the server? Has anyone else run into the same issues and how did they take care of it?

Below are the lines of code I took out of the config files from notepad so you can see what I'm referring to:
