RE: Cannot connect to Management Reporter
We bumped into this specific problem with a new laptop being added at a client site recently. Prior to that I hadn't seen a SOAP authentication failure. Turns out the problem was that the server Management Reporter was installed on had a computer name that was longer than 15 characters. This created a problem with some, not all users connecting with the machine.
I found the following post in the forum: community.dynamics.com/.../129747
And a Nerdier nerd than I implemented something similar to this portion of the recommended fix...
setspn -S HTTP/MRservername domain\customAccountName
setspn -S HTTP/MRservername.fullyqualifieddomainname domain\customAccountName
Be kind to the nerds in your life. What's necessary here is to make the server visible to the workstation.
