Accessing of Shared Network Drives through a PPoE Service

Good Day,
Could anyone suggest how I might be able to do File Sharing on a Mikro Tik Router Board RB 133c, between the ethernet and wireless port. I am using a PPPoE Logon on the Wireless Side.
There are some network drives that I have mapped to a laptop, that connects via its WiFi Node. I need to connect the mapped drives to the Network drives, once I have logged on to the PPoE Server.

Can anyone help me, or suggest a way of getting this right.

There in no broadcast ,and windows can not automaticly detect network file shares.
You must type ip address i address bar example.. \192.168.1.5 not host name of computer (there is no brodcast to resolve host name to specific ip)
and you will see file share of that computer!
Check firewall to pass ports 135-139 for file shareing
