I have been struggling with an LACP implementation for a while now, and the number of variables has really been getting overwhelming.
Right now the setup I have is two hosts running 2008R2, each of which are connected to a Force10 S50 switch.
On the switch I believe LACP is setup correctly and dynamically.
Using the advanced Intel drivers, I have dynamic aggregation set on both hosts. Each host has a Pro/1000 PT LP NIC attached and I am aggregating 2 1gig lines.
The problem arises when transferring test files. Task manager shows a maximum 49% use of the 2gbps teamed line.
What could be causing this behavior?

That's normal. With a single stream of data over an LACP bond, only 1 connection will be used.
LACP is useful when you have multiple data streams traversing the link and for active/active connection redundancy. Try copying multiple large files to/from different destinations and the utilization should reach close to 100% if it is configured correctly.
