A speed problem on XP2 to XP2 network

Hey all-
I recently upgraded my previously functional xpsp2-win98 network. (Print,
file share all worked great, and fast!)
Now I have an XPsp2-XPsp2 network.

I have configured my xp to xp net as per MS directions and have a terrible
lag and or loss of network speed (the connection icon on tool bar shows a
data rate of ~ one byte every few seconds????). I have turned off firewall
and no difference.

Also, I can find the network printer (from machine 2), but it won't print
from machine 2; machine 1 is instantaneous and reliable when test printing.

The firewall (on machine 1, which is connected directly to printer) says it
is configured for file/print sharing on my network, but..... No printing
from machine 2!

SO: how to fix speed ocross network? How to configure/install printer to
machine2 for printing?


Thanks for any 'real' help......
