SMB1 disabled -- no workgroup available

I am receiving this message after smbclient -N -L \\
does any one could help me to figure it out?
it is a temporary problem of the target machine or I am doing something wrong.
This will cause at the end of the excercise when I execute: administrator@
[-] SMB SessionError: STATUS_LOGON_FAILURE(The attempted logon is invalid. This is either due to a bad username or authentication information.)

Thanks in advanced.

Smb v1 is disabled on modern versions of windows so if you’re using something that uses smbv1 then that explains the first error.

The second error seems pretty straightforward. Its saying your credentials are invalid. Seems like you have the wrong username or password?

Personally I find to be more reliable than btw so might be worth trying that as well

I suggest you just use the following command line (on Linux):

smbclient \\IP\folder

In my case, the folder was WorkShares (the answer to the task 5).
