OK I had a consultant come in to rip out an abandoned server out of our tree and then start from scratch and premigrat it back into the tree to replace a slower Border Manager 3.9 server. We had oringinally 4 servers in the tree, 3 in the main context "Context A" and 1 in another context "Context B". When looking through all my servers to make sure they are still in timesync, I see the 1 server in "Context B" shows all servers in sync but also gives an error that it can not time sync to the server the consultant ripped out.

What do I do? Where do I start?
