Reach/initial connection of the share is fine. Can render directory list. Can even download off the share (copy/cut from it, paste local). But.. trying to upload (copy/cut local and paste there) sees the transfer start and remain at 0%. Windows explorer halts. explorer.exe and a few threads become 'unkillable'. Off another workstation/Microsoft Windows instance. Works fine. It's this machine. Windows 10. Not firewall/network related.
Only over VPN. On it locally/on LAN. No issues.
Strangest thing..... Anyone got any thoughts ?
