It would be helpful if you tried accessing \\Macbookpro-570f\abcd\ from explorer to check if there is a problem with the network or share setup. (Update your answer with the result).
My first thought though is permissions. Access requires sufficient permissions to create its .ldb file in the same folder as well as being able to modify the .mdb file. Windows shares have 2 sets of permissions that apply. First is the permissions on the share, second is the actual NTFS permissions on the file / folder. You need to ensure that BOTH of these permission sets grants the correct user sufficent permissions to modify the mdb and create the ldb.
