2 Devices WiFi Browse Okay, No Lan with BS Player or ES File Explorer

I'm able to connect to my home wifi and use multiple browsers on both my Galaxy S3 and Galaxy Tab 10.1

I HAD been able to connect in LAN mode to my PC on both BS Player & ES File Explorer to my computer.

When I do a scan for the servers my PC IP address shows up but I can no longer connect.
I am using a server name instead of just the address numbers.
I have folders shared on the PC and have a user name and password set up in W7.

I've uninstalled the Android apps & reinstalled. No good.

Frustrated.
What now?
