No, no previous existence. I thought the same thing...perhaps it was first installed with an evaluation copy of SQL Server but don't believe it to be the case. In any event, since it was installed on 3-nodes at the same time in February...and it's been 305 days since the install, it far exceeds the 180-day trail period. The other 2 nodes appear to be fine.
