Problem Description: An error in lockdown installer caused (error was caused by bug CF-4202932 left wsconfig running while running lockdown installer) a rollback of the settings. After rollback any request to IIS caused a 500 server error. The site able to serve cfm files and static files before running lockdown installer, afterwards any request would trigger a 500 response:

HTTP Error 500.0 - Internal Server Error
Calling LoadLibraryEx on ISAPI filter "C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_filter.dll" failed

Note that this is the 32 bit version of the aspnet_filter.dll there was both the 32 bit and 64 bit version in ISAPI Filters at the global/serverwide IIS level.

Steps to Reproduce:

1) Installed IIS and setup a single web site (
2) Downloaded latest (refreshed 2018,0,0,310409) public beta CF installers
3) Ran CF installer
4) Logged into CF administrator
5) Ran wsconfig as administrator and connected the single website (I did not choose all IIS sites).
6) Important - don't close wsconfig to trigger the bug
7) Tested a cfm file through IIS
8) Ran Lockdown Installer, finished with errors.
9) Hit test.cfm again

Actual Result: 500 server error from IIS

Expected Result: 200 OK

Any Workarounds: I went into IIS ISAPI Filters and deleted the 32 bit filter and requests were able to run.
