Could be the firewalls.

Might also be that you usually need to search for new "network places", but you're assuming they show up automatically?.

Can you both access the internet?

Can you ping between the machines?
If you are not sure how to do this, then the first thing to do is to go to a command prompt ([Start][Run] then type cmd) and type
ipconfig
on each machine. This will give you the IP address of that machine. Then, in a command prompt on the other machine type
ping <ip address>
using the ip address of the opposite machine
e.g.
ping 192.168.1.1

This will either give you responses, timeouts or host not reachable errors.
If you get responses from either machine then you have network connectivity between the machines and there is something else stopping the share access.
If you get no responses, try temporarily disabling the firewalls on both machines and then trying again. If you get responses this time then it is probably your firewalls, again (try accessing the shares again before you re-enable the firewalls to confirm this).

If not then can you post back the IP addresses and subnet masks of the machines (so we can check they are on the same subnet).

Post back how you get on then either myself or someone else can help your further
