Thank you for your prompt response. I believe I enabled SMB 1.0 just for Heresphere. Based on that I disabled it as its a security risk and its no longer needed. I had rebooted the headsets repeatedly, no change. Rebooted windows, no change. Rebooted router, Quests all connect now. Didnt have to recreate the SMB share.
Many thanks, love the program.
