I ran into a strange error recently on an Exchange 2013 server. The WWW Publishing Service was stopped. When I tried to start the service it failed on a dependency. A quick check revealed the Windows Process Activation Service (WAS) was stopped. When I tried to start WAS I received the following error.
The Event Viewer was littered with equally cryptic Event IDs, such as WAS 5005 and WAS 5036.
Not the first time
I’ve actually encountered an error like this before. I am not sure what causes it. But evidently something in Internet Information Services (IIS) becomes corrupt. [Read more…] about Windows Process Activation Service – Error 13: The data is invalid
