Question : Problem: Split Pair Wiring at 10Mbps

I ran into a situation where a building had been wired already.   When I tested the line, which was a direct line from the drop to the server room, it returned a 'Split Pair' indication.  All 8 internal wires were being used, per drop.  The client machines would only connect at 10Mbps.  Any idea why the previous company would have wired this way?
