My web application was running absolutely fine. Just 2 days back, I got an error saying. SERVER APPLICATION UNAVAILABLE
I am pretty certain that nothing was changed on IIS. Unless my automatic Windows updates screwed it up completely.
My event viewer had zillions of following errors in Application category.
aspnet_wp.exe could not be started. The error code for the failure is C0000005. This error can be caused when the worker process account has insufficient rights to read the .NET Framework files. Please ensure that the .NET Framework is correctly installed and that the ACLs on the installation directory allow access to the configured account.
I reinstalled IIS. After installing, i ran aspnet_regiis -i for framework v2 and now it throws error saying - The application could not be initialized properly.
Any ideas what going on?
