jayrod,I am using ES File Explorer 1.4.1, when adding a new LAN share are you only adding the server IP or server IP/sharename.If I put server IP then I can save, if I put server IP/sharename it give me an error. If I click on the new share (using only server IP), it said my username/password was incorrect. But eventually I managed to get working.Here are troubleshooting I used1. Goto Control PanelNetwork and InternetNetwork and Sharing CenterAdvanced sharing settings, turn off password protected share (this can confirm whether it is username/password problems)2. Change username password3. Create a new share and then change username password4. Update ES share settingsIn Windows I don't use HomeGroup.
