Most likely causes:
· The worker process is unable to read the applicationhost.config or web.config file.
· There is malformed XML in the applicationhost.config or web.config file.
· The server cannot access the applicationhost.config or web.config file because of incorrect NTFS permissions.
Things you can try:
· Look in the event logs for information about why the configuration files are not readable.
· Make sure the user identity specified for the application pool, or the authenticated user, has the required permissions to access the web.config file.
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.
After researching this issue I was able to determine that the issue was being caused by an incompatibility within theDynamicCompressionModule used by II7. This module was utilizing a global compression schema schema that was not compatible with the our 32-bit application. This schema was being set in this case by WSUS and Sharepoint. So in plain English this boiled down to a server configuration issue brought about by these applications running an incompatible dynamic compression schema which resulted in the error seen on iMIS15.
In order to identify this issue I did the following:
1. I ran the following command from an elevated command prompt.
%windir%\system32\inetsrv\appcmd.exe list config -section:system.webServer/httpCompression
It returned something along the lines off.
