If they have no default gateway, then they won't have Internet access. Are the two 7 machines set to obtain settings automatically in their NIC?
Since your Vista computer can connect, look at its default gateway and DNS servers. 169.X.X.X IP addresses usually show when the computer does not obtain any DHCP settings.
So, are the 7 computers set to automatic obtain information? Are their DHCP Client / DNS Client services running?
One option you could try is manually enter the default gateway & DNS address listed on the working Vista machine into the NIC settings of the two 7 machines.
Can you attach a copy of the IPCONFIG /ALL settings for each of your computers here?

How do I change the settings on my Vista computer to allow them access?
