MN-500 do not allow 3rd computer thru

Hi there,
my MN-500 does not allow a 3rd computer through to the network.
It does have DHCP server enabled.
LAN has subnet mask 255.255.255.0.
All 3 computers are connected to MN-500.
However, the 3rd computer cannot access internet, while the first 2 are fine.
Can anyone help?
Thanks.

don't bother.
I played with the dhcp starting/ending addresses, and it worked.
I guess it must have reset some internal settings somehow.
thanks everyone.
