Thanks for you response PCPiranh.
I have two of these units that were bought at the same time. They are used for backup in a Windows only atmosphere. I do not map drives to these units. That becomes a problem depending on who is logged in. They are reference \\server\username only. The one in Texas is 100 % functional. If you have the rights to access these folders you are in, otherwise it prompts you for a login. The one in New Jersey works fine if you don't enable "Access Restrictions", of course no restrictions to anyone. If you turn on "Access Restrictions" and assign access permissions it will not let anyone in. What is really confusing is that I can see the Active Directory of all users in order to assign permissions. So the device does recognize Active Directory. It appears that it is not picking up cached credentials when you try to access the folder. It also does not respond to the login window using Active Directory or local login. Another interesting issue is that every time you add a user or modify a user that has no description defined it will default the description field to the first user name every time. I deleted the first user and recreated him with no change in this issue. Now if there is a Description it will not change it. This is really a non issue. I mention it because I thought it might be related. .
I have Init the system and updated to 2.16. Neither of which helped at all. I am really at a loss as to what else would work.
I am really impressed with these units. The one in Texas has been trouble free for many years now.
I am really at a loss as to what else I might try.
