I've got Server 2012 R2 running in Hyper-V with Exchange 2013 installed. It's not a critical system - I'm using it to learn Exchange administration.

I went to log into the server tonight after several months of not touching it, to discover that four services are consistently failing to start no matter what I do. The World Wide Web Publishing Service error seems to be commonly caused by a the AppPools folder missing from C:\inetpub\temp\, but that is not the case for me - I've already checked twice.

The services are:

  • Net.Tcp Listener Adapter
  • World Wide Web Publishing Service
  • Net.Msmq Listener Adapter
  • Net.Pipe Listener Adapter

In the event log are the same four errors over and over:

Event ID 5036, Source WAS

The configuration manager for Windows Process Activation Service (WAS) did not initialize. The data field contains the error number.

The error number listed is 0D000780.


Event ID 5005, Source WAS

Windows Process Activation Service (WAS) is stopping because it encountered an error. The data field contains the error number.

The error number listed is 0D000780.


Event ID 7023, Source Service Control Manager

The Windows Process Activation Service service terminated with the following error:
The data is invalid.


Event ID 7001, Source Service Control Manager

The World Wide Web Publishing Service service depends on the Windows Process Activation Service service which failed to start because of the following error:
The data is invalid.

I strongly suspect you've got malformed XML in your applicationHost.config file. I'd give that file a once-over as a first troubleshooting step.

I ran the following command

(from C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727 or your version):

aspnet_regiis.exe -GA domain\username

and then restarted IIS.

It seems to be an app pool issue if you sysprep or moved configs

I agree with Evan. You can restore the applicationHost.config from backup. Check here for the process. https://supertekboy.com/2015/02/16/windows-process-activation-service-will-not-start-error-13-the-data-is-invalid/
