Large file copy starts great, then brings box to knees

I'm baffled. Windows Server 2003 Standard Edition, all updates applied. I
can copy large files from this server to other machines on the network just
fine, great speed.

When I go to copy a large file (> 2GB) to this machine it starts out great,
but after about a minute or two the speed of the transfer slows greatly and
the entire box becomes very sluggish.

I started monitoring this to see what was happening. I look at the task
manager resources and I notice that as soon as I start the copy (either
locally or remote) the physical memory (k) available memory starts decreasing
in 30-50k chunks until it brings it all the way down to about 2-3MB
available. The machine starts to tank at this point. As soon as I kill the
copy, the available memory jumps right back up and the box resumes normalcy.

I've experimented with other windows server 2003 machines I have, this
doesn't happen there.

What in the world?
