After installing and deploying office web apps on an existing sharepoint 2010 farm, I'm facing an issue with PowerPoint web App.
Namely when I try yo open a presentation in browser, after maybe 30sec I get the following message : "Network connectivity has been lost. Check your network connection or try again later.". I looked into the SharePoint logs and I found multiple iterations
of the following record :
Windows=False, Ntlm=True, Digest=False, Basic=False, Anonymous=False 85c0870e-4a45-4266-96be-c28495c122a7

More interesting I found the following entry Windows Application Log:
