make sure that you don't have personal firewalls set up on either computer. (zone alarm, norton personal firewall, etc.) even the built in windows firewall can mess with that .....START>CONTROL PANEL>NETWORK CONNECTIONS>LOCAL CONNECTION(or whatever you named it)>pROPERTIES>ADVANCED.
you may or may not be able to use the firewall and have the two computers still play nice, just by enabling the other computer to be able to cross the firewall....
hope it helps.
.... another note! even if you have zone alarm disabled, it'll still screw up your networking.. you have to uninstall it altogether, or make provisions for it to allow your other comp to work.
adios
