sometime this
python crackmapexec.py -t 100 192.168.200.0-255 -u admin,guest,administrator -p admin,password,1234,guest,user,administrator --shares

That seems to be an Impacket bug when negotiating against a machine that has those International characters. Please fill up a bug at https://github.com/CoreSecurity/impacket/issues

[byt3bl33d3r]

@its0x08 this is a bug with the impacket library, just filed a bug report

[asolino]

@its0x08 I just fixed this issue, could you please recheck so I'm sure it's fixed correctly? You will need to git pull the latest impacket repo.

[its0x08]
