After upgrading from 2008R2 to 2012 my IIS applications stop when accessing them. I found the following errror in the event logs:
Log Name: Application
Source: Microsoft-Windows-IIS-W3SVC-WP
Date: 12/10/2012 11:05:09 AM
Event ID: 2280
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: XXXXXXXXXX
Description: The Module DLL C:\Windows\system32\inetsrv\rewrite.dll failed to load. The data is the error.
If I repair the IIS URL Rewrite Module 2 in Control Panel everything works again. Any idea what would be causing this? Everything is working prior to the OS upgrade.
