Firewall blocking file sharing

Came into the office today (two computers on the network) and one of the computers could not see the other on the network (it was not a problem the other way around). I went through some troubleshooting, and figured out it was the firewall on the one computer blocking access. The firewall is controlled by MacAfee virus protection. So, I turned off the firewall, and bingo, I cann now see each computer from both directions. The problem is now I don't have any firewall protection. Any reason the settings on the firewall would have been different today than they were yesterday, and how do I turn the firewall back on while allowing the file sharing to continue on as before over the network?

Sounds like an issue with McAffee. Have you checked the McAfee support pages and/or forums?
