I'm having a difficult time getting ColdFusion 9, IIS and Plesk to play nicely together. So far, I can install ColdFusion Enterprise 64bit and everything is fine. I can access CF Administrator, add data sources, and everything else. Just one minor problem... It breaks access to Parallels Panel 10.4 and IIS throws errors ranging from 400 to 500.x... Here's the most recent one (among many others I've seen)... Module: IsapiModule Notification: ExecuteRequestHandler Handler: AboMapperCustom-36785 Error Code: 0x800700c1 Requested URL: https://localhost:8443/ Physical Path C:\Program Files (x86)\Parallels\Plesk\admin\htdocs Logon Method: Anonymous Logon User: Anonymous I've run "Repair Plesk installation" using the PP Reconfigurator many times which fixes the problem and restores access to the Parallels Panel admin BUT doing this breaks ColdFusion!!! It's a catch 22. I've tried everything and I've spent days going back and forth making one work while breaking the other. I'm urgently trying to move a handful of sites over to this new system but Plesk insists on throwing up roadblocks. Any Ideas?
