Windows 10 Upgrade and IIS 503 Errors
IIS Rewrite Module Problem
It turns out that there’s a new version available that’s more recent (but doesn’t change the version number), and that needs to be installed in order to work. The version I found on the WebPI was dated a month ago (5/27/2015), and I suspect it’s meant to address just the type of problem I’ve been running into with my upgrade.
To install the module:
- Uninstall the Rewrite Module from Windows Features
- Go to the Web Platform Installer
- Pick Url Rewrite from Products | Server section and install
- Restart IIS
