You may be able to address that by increasing the baseline route-cost field
in the properties of the wireless connection.  When both datalinks are
live, your route table will naturally favor the wired interface.

Or, using there's always the various ways to disable the WLAN connection,
including letting XP do it automatically when the machine's docking-state
changes.

I've observed that on my own system, a TabletPC from Motion Computing running
the Tablet version of Windows XP, that the wireless connection is preferred. If
I have both connections active, the (faster!) wired connection loafs while most
traffic goes wireless. I haven't found a place to change this behaviour, but I
haven't looked too deeply, either. But it bears strongly on this discussion, I
think.

My own sense is that as wireless becomes more and more widespread on
campus the idea of saying you would allow ftp on an intranet  "wired"
connection but not allow ftp on wireless or extranet connection becomes
a helpdesk nightmare. My application worked but then it didn't.
