A little while back I added an NAS to our network; an NAS in simple terms is a Hard Drive that sits on the ethernet network. Sitting on the network allows all computers on the network to use the drive. I use a Simpletech Simpleshare 250GB drive that I bought at Sam's Club. The drive was very easy to setup and use...until I added Microsoft's Windows Live One Care.

The firewall in WLOC killed access to my NAS. The firewall was protecting me from my data!!! After a quick call to tech support for WLOC, a solution was offered. Under the ADVANCED options, enable the following protocols: all DHCP and all ICMP entries.

This fixed my problems; I'm not sure what other problems might arise from enabling these protocols but the tech support person told me the system was still very sound.
