Seems to me that 192.168.56.1 as said by Paul Smedley is correct.

Hi Wim, as said, the thing is that the resource is available at a "smb:>" prompt in an OS2 command window, and (also said), if it is available there must be available in NetDrive. The issue could also be -just guessing- the password request that I skip just by hitting RETURN :
smbclient \\192.168.56.1\Users
gethostname failed
gethostname failed
Enter WORKGROUP\GUEST's password:
here I hit RETURN and I get this :
Try "help" to get a list of possible commands.
smb: \>
then I command smb: \> dir
and the requested resource's folders are available . DR 0 Sat Jul 7 13:06:16 2018
