Registering ASP.NET for Office Web Apps Error

Here's a quick and dirty post for something that came up recently in the lab.  I was setting up an Office Web Apps server, and was getting the following error:

Can't create new Office Web Apps farm: The server must be joined to a domain.

Seeing this error message was a bit frustrating to say the least, because the server was indeed joined to a domain.  After a bunch of searching with Google, I finally came across the answer.  While setting up the server, I had installed IIS before .NET, so I needed to register ASP.NET.  The required bits in IIS were already installed, so it was just a matter of registration. This can be done with the following steps:

• Open an elevated command prompt or PowerShell console.
• execute the command start Microsoft.NET
• navigate to c:\windows\Microsoft.NET\Framework\v2.0.50727
• execute the command asp_regiis.exe /i 
• execute the command iisreset or restart the server

Other things to check for when getting this error are to ensure that your server really is connected to a domain (and that the server account in AD is not broken) and that you have the correct DNS Server specified in the network settings.
