Get a 'net usershare' returned error 255: net usershare add: share name mike is already a valid system user name' on sharing my server, so it can appear on (mainly) windoze 10 machines.

The server itself uses Ubuntu 14.04 LTS.

Please help me.

The error message seems to be pretty clear that "mike" is already in use. Have you checked for the other "mike" that the system is seeing?

More information would likely be useful. You might want to look at this, if you haven't already done so: http://www.linuxquestions.org/linux/...Ask_a_Question

I did a
mike@server:~$ cut -d: -f1 /etc/passwd

root
daemon
bin
sys
sync
games
man
lp
mail
news
uucp
proxy
www-data
backup
list
irc
gnats
nobody
libuuid
syslog
mysql
messagebus
postfix

mike
usbmux
lightdm
dnsmasq
avahi-autoipd
hplip
kernoops
pulse
rtkit
saned
whoopsie
speech-dispatcher
tomcat7
hale
sshd
mdh
mike@server:~$

and there's only one 'mike' in the list.

How do I check what powers are attached to mike?
The user mdh I created as well. Not logged in with user mdh yet as the system says it's blocked.
