Problem with routing

Hi All!
I install Mikrotik in pc have 2 ethernet. a netcard connect to network 192.168.1.0/24, another netcard connect to 192.168.2.0/24.
from a PC 192.168.1.5 ping to 192.168.2.1 is good but when i ping to a PC have IP 192.168.2.5, it request timed out.
pls help me to solve! thanks.

routing is fine. simply switch off Windows firewall (or another firewall) on 192.168.2.5 =)
