I'm not on a Linksys, though it looks like I'd rather be bc of the extra options. Thanks for your suggestion, RoadClosed. I ran a wizard from the firewall that scanned for all computers connected to the network and added what it found (the other comp) to the trusted zone. This should keep me from seeing errors from now on when the two computers try and connect. Thanks a lot to both of you for your help! Now I'm much more familiar with how my home network functions.
