- What did you do yesterday?
- What will you do today?
- Are there any impediments in your way?
We'd limit the role of "Scrum Master" to really be the meeting facilitator and the person who records that the answers to these 3 questions were reflected in the TFS work items' changes and if not to follow up and do it themselves or ask the other team member to do so. See http://www.mountaingoatsoftware.com/daily-scrum and http://www.mountaingoatsoftware.com/scrummaster for some info.
Ultimately its an effective way to work as a team of peers using TFS out-of-the-box, to deliver in accordance to the project plan and methodology guidelines that the project manager has committed the team and to empower the leadership/customer to have full project vision and management capabilities as they wish.
