I have a totally fresh install of Windows Server 2008 R2 Standard Edition and have applied SP1 to it (not slipstream).
It is a member of company domain and I'm logged on as domain administrator.
Now I'm trying to install the full suite of DFS roles. I can install them all except for "DFS Namespaces". When trying to install this role it gives me an error code of
0x80070643. Then asks me to reboot before trying again. Of course I have tried it numerous times and always hit this error.
I've taken a screenshot of the error here: http://i.stack.imgur.com/kld33.png
