SMB share: access is denied

Hello,

Can you, please, help with any further suggestions?
After initial configurations I'm still getting the follwing error message when attempting to connect to a password protected SMB share from Windows:

Jul 31 20:47:33 s11 smbd[599]: [ID 812811 daemon.notice] logon[s11\user1]: LOGON_FAILURE
Jul 31 20:49:37 s11 smbsrv: [ID 421734 kern.notice] NOTICE: [S11\guest]: files access denied: guest disabled

Note: I sucessfully list the share from Windows, for example:

C:\> net view \\s11
...

The share is as follows:

s11# zfs get share
NAME                                          PROPERTY  VALUE  SOURCE
tank/data                                     share     name=data,path=/tank/data,prot=smb  local

Perhaps I'm entering credentials in the wrong way in Windows (?):
