You may be in the situation that ColdFusion services are not starting up and a manual startup yields no useful information, too. It simply failed after it tries to startup the services for a very long time. If services are starting up it may takes an extreme long time to start.
Start-Service : Failed to start service 'ColdFusion 10 Application Server cfusion (ColdFusion 10 Application Server cfusion)'. At line:1 char:1 + Start-Service Cold* + ~~~~~~~~~~~~~~~~~~~ + CategoryInfo : OpenError: (System.ServiceProcess.ServiceController:ServiceController) [Start-Service], ServiceCommandException + FullyQualifiedErrorId : StartServiceFailed,Microsoft.PowerShell.Commands.StartServiceCommand
Background:
There are for sure more possible situation that may cause a ColdFusion startup failure, but if you have not changed anything and only rebooted/restarted your server/coldfusion after some OS updates and ColdFusion is now failing to start without having anything changed in ColdFusion you should check this issue very first. From my point of view this issue here is the most common issue that everyone will experience sooner or later.
