Can't access shared folders on NAS

[TASC-ITDept]

We have a TeraStation Pro TS-RHTGL/R5 (F/W 1.26) set up as RAID5, Array 1 = 451.38 GB / 1394.10 GB (32.38 %) on our domain with a Static IP for last 6-7 years.  AppleTalk and FTP are disabled.  The NAS is only used by Win XP, 7, 8 & different Win Server versions.

We had a power outage that lasted longer than our battery backup.  We were able to boot the NAS back up just fine and we can bring up the Web interface and log into the NAS, but can't browse to NAS to view the shared folders through Window's Explorer. 

Under Disk Management we ran the Disk Check and it was successful, but we still can't browse to see the folders.  We do not want to lose the data on the drives, so we haven't made any changes yet; such as removing from the domain and adding it back or anything else.  We would rather not purchase 4 more drives until we know a little more, and if that would even help get this unit working again.

Has anyone else experienced this?  Were you able to resolve it easily? 

Thanks, AJ
