Smb/sftp not working after ethernet port change

How would one go about re configuring network connection? I installed new gigabit Ethernet card and was finally able to get the webend to connect. However having issues with getting samba and sftp to work. Windows can see my “shares” folder and will attempt to connect but authentication will not work(windows keeps popping the same user/pass screen up without connecting). same with sftp…

I have double checked user/group info on samba settings, checked the shares folder permissions, rebooted both server, and client machine, turned off and on samba setting, deleted samba share folder option, then added it back as a new export…

any help please and thank you

also can someone please explain the “wheel” group to me, or point me to where I can learn.
