After 6.10 update can't access smb shares

Hopefully someone can help I updated to 6.10 as prompted and now my win 10 pc can't access shares. If I go to access them through windows explorer I put in the correct password but it just won't accept it it prompts me again to enter the password. These shares don't have a password. I installed smbplus just in case that is needed still no change. It has annonymous ticked. I created a new share and still the same issue I don't map the drives I access them through the ip address or name of readynas.

 

If I try to map drive using net use it prompts user name or password is incorrect because there isn't a password.

 

I can access the nas through the webbrowser.

 

Any suggestions you would think they would test things like this before realising dodgy firmware. 

 

EDIT: It works now as this is a office backup the update must have cleared the ADS files so on changing to local users it works now. I will have to take it to the office to do another sync. 

 

Thanks
