My hunch is that one of the things that the AOL software may have
done (and left behind) is to reduce the MTU on the Win2K box from the
~1500 typical of LAN settings to the ~576 typical of dial-up. That
should work, if with less-than-stellar performance, as long as
winroute has no problem fragmenting and reassembling packets --
something NT itself is reputed to have problems with sometimes.
You can find third-party "tweak your MTU" utilities, or you can
search the registry to look for the setting and correct it.
[Even when Windows isn't involved, the "small packets pass, large
ones don't" symptom almost always means an MTU/fragmentation issue.]
