I have a SharePoint (2010, Standard edition) farm with three site collections. On each site collection is a Word Automation service associated.

Let's assume each sitecollection listen on different ports:

  • 80
  • 90
  • 100

When I try to convert a Word document to PDF with the Word Automation Service via PowerShell it will succeed on port 80, also on port 90.

But not on port 100.

So I checked the permissions for the service and the database. Both are set to the application pool identity.

I didn't get any error in the ULS that helps me out to figure out the problem. Does anyone have an idea that can explain the problem?

  • Can you use Set-SPLogLevel -TraceSeverity VerboseEx, then repeat and see if you can find any errors with WAS? Use Clear-SPLogLevel once you've completed your test.

I think I solved the problem. The Issue was, that there existst three databases that couldn't be upgraded.

Because in the log I got sometimes upgrade error messaged.

The database that couldn't be upgraded, wasn't used by any Serives and are obsolete. So I deleted them and after this it works perfect.

I wondered why this can accour a problem with the word automation service.
