replication

I am configuring master slave replication between two servers.

First Server A is master on localhost Xampp, and B is slave server (web server).

Master Server is properly configured but having issues with slave server.

ERROR:: Unable to read master log position. Possible privilege problem on master.

What master IP address should I configure for slave server, and how should I rectify this error?

Thanks in Advance!
