IIS 7.5 App Pool Stopping: Rewrite.dll broken

posted Oct 18, 2013, 5:04 AM by Eric Patrick
Upgrading to Windows 8.1, I found that IIS stopped working; the application pool would be stopped under rapid fail protection. The Windows logs indicated:

The Module DLL C:\WINDOWS\system32\inetsrv\rewrite.dll failed to load.  The data is the error.

Googling this phrase led to a technet solution:
  • From Control Panel > Programs and Features > IIS URL Rewrite Module 2, right click and choose Repair
Simple solution; long time to find it.
