Hi billygetsmail, welcome to the WD Community. Make sure the laptop is on the same workgroup as the My Book Live. You can also try using the Discovery tool to find the My Book Live on the network.
Check page 67 of the manual for more information how to find the My Book Live workgroup, by default the MBL will use the “WORKGROUP” name.
