Change of domain on Easystore NAS running AD mode

I've recently rebuilt an SBS 2003 box after (imminent) hardware failure, and for various reasons have given the box a new internal domain name - still pickup up the same mail and serving the same clients - all rejoined without issue.

I do have a problem with an Acer Easystore (2Tb), which is connected to the old domain. If I disconnect and "leave it swinging", I can get NO access to the shared folder as there is no AD to authenticate against - I get message "the security database on the server does not have a computer account for this workstation trust relationship"

I've managed to regain access to the box by changing the IP of the server originally registered to the NAS, but the software on the NAS wont permit a change of domain for AD authentication.

Before I strip off over 3/4 Tb of info to cradle drives and re-initialise the NAS, can anyone offer a simpler, more engineer friendly solution? I really need to change the domain this system is authenticating against, but there seems to be no option in the provided interface.

I have been unable to get even an acknowledgement from Tech support at Acer.

I wonder whether the operating system on this NAS is Linux or some derivative (busy box? - the only info I can find on the "internals" of this box is that the chipset is an Intel® 8MB NOR Flash), and if so, is there another way into it? - Im no Linux expert; but I'll have a try, and maybe learn something as well!

Any help please?

Thanks Zelron, but no.

That is actually what I'm trying to avoid. According to the Acer docs, it seems to be necessary to re- initialise the disks in order to to join an AD, and this would, of course, delete all the data currently stored on the unit. I am trying to keep the data stored and REJOIN the store to a DIFFERENT domain. Updating the firmware also normally has the same(or similar) effects.

OK - for info only - in case any OTHER poor sod has to do this!

I backed up the ENTIRE .75Tb onto cradles and confirmed data was secure - then used the interface to change the authentication method back to Local authentication mode, taking due notice of the dire warnings about everything being deleted.

Pressed the "Change" button ,and about 30 seconds later the server came back up with all the data STILL available in the Public folder!

SO, either there has  been an early christmas miracle, or Acer dont know how their own equipment works; either way, Ive got a result, but only after a lot of needless work.

Almost the definition of IT support isnt it!

I'll close the question and allocate some points to Zelron, just for trying I think! - cheers bud.
