I tried to map a network drive to my computer. Windows 10 could not reconnect it after updating from Windows 7. So I assumed, something changed between the two windows versions and tried to reconnect the network drive manually:

net use Y: \\servername\Public /Persistent:Yes /User:Guest

Always got system error 1240.


After a while I researched in my smb.conf files of the server which said, that guest logins were not allowed…

Using a user mentioned in /etc/samba/smbpasswd, the net use command succeeded.

I do NOT want to talk about it… ;-)
