DNS in diferent networks

[fuse]

Hello,
I have enabled ebox dns like mylocal.lan
When i access some pc.mylocal.lan that is in the same network 192.168.10.0 from a computer on 192.168.10.0 it works fine, but if i try to access to pc2.mylocal.lan that is 192.168.22.0 from a computer 192.168.10.0 it does not work i got ebox error,
    "Unable to determine IP address from host name for pc2.mylocal.lan "

But if i got windows command line and ping pc2.mylocal.lan it works fine, what am i missing?

Thanks
