More recent versions of #Windows try to enforce security in some kindof dumb ways, and one is that if you're attempting to access a Samba fileshare that doesn't require credentials, you might get something like
{F2515 size=full}
To solve, you need to allow "insecure guest logins" for remote shares . You can do this via either:
* {nav gpedit.msc > icon=desktop, name=Computer Configuration > icon=folder, name=Administrative Templates > icon=folder, name=Network > icon=folder, name=Lanman Workstation > icon=file-o, name=Enable insecure guest logons}
* `reg add HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters /v AllowInsecureGuestAuth /t reg_dword /d 00000001 /f`
