To fix this, you need to understand the problem first:

The two machines are on different subnets altogether, and unless there is
a gateway between the two subnets, you cannot directly reach one from the
other. 

A machine on 192.168.28.x with a netmask of 255.255.255.0 can directly
reach only machines in that subnet. A machine in 192.168.29.x cannot reach
a machine on 192.168.28.x.

You have three choices: 

- put all the machines on the same subnet

- change the netmask for *all* machines to 255.255.0.0 from 255.255.255.0

- set up routes on a gateway machine that has IP addresses for both
subnets so that it can route packets from one subnet to the other.

The last is the simplest, the first will create the most traffic and will
kill you LAN's performance, and the second one is a kludge.

Pick up a copy of "TCP/IP for Dummies" - that will clearly explain to you
how the TCP/IP concepts work.

Hope this helps.
