Access denied on a single Share

[TMDolphin]

Hi there
Since some days i've a problem that i never had before accessing one of my share. So all the other shares are accessible. I always get a Message Access Denied on this single Share. Special on this share is, that i use Windows offline files to have it avaiable offline as well. I mapped a network-drive to this share via \\HDA\share.. accessing the share via \\IP\Share works well.
Is there someone who has a idea for that issue?
Thanks for your Help

Check the file permissions and ownership. All files need to be chmod 775 and owned by your first admin user.
