If suddenly the share folder you access for a long, stop working, you have to erase the credentials stored to your computer. One option is to do it by CPanel > Credential Manager, believe me tried, even deleted from there, couldnt access the folder. Deleting the stored credentials by the DOS net use command made the trick!
List all stored credentials -> <code>net use</code>
delete all the stored credentials -> <code>net use * /delete</code> or
delete only the entry for a share <code>net use \\192.168.2.43\data /delete</code>
then you have to go to mycomputer choose 'map a drive' (maybe ‘Connect using different credentials’ is helpful)
