Scan to network folder from Ricoh MPC2800

Our office uses a Ricoh Aficio MPC2800 for copying, scanning, fax, and printing.  Prior to a recent power outage, we could scan to a shared folder on two individual workstations or four shared folders on our SBS2011 domain server.  After the power outage, we can still scan to the workstations but cannot scan to any shared folder on the server.  The error message from the connection test at the MPC2800 console is "connection with the PC has failed.  Check the settings."  The print and fax features are fully operational.

We have tried the following:
Verified the username and password of the authentication account for the shared folder.
Added rule to allow the MPC2800 I.P. address to pass thru the firewall.
Disabled server firewall.
Created a new shared folder on the server with new connection on the MPC2800.
Removed and recreated share name and privilege on one of the shared folders on the server.
Configured folder path on MPC2800 using server's I.P. address instead of name - ipaddress\sharedfoldername
Configured folder path on MPC2800 using path displayed on server share information - servername\sharedfoldername
Compared network settings on workstation to network settings on server - subnet, gateway, dns, etc
We have two MPC2800 units on our network.  One unit was taken off the network during the troubleshooting activity.
Contacted local Ricoh support.  Their suggestions are included in the above.

Other observations and information:
The workstations are running Windows 7 Pro.
Some of the shared folders on the server are also mapped on the workstations without any access restrictions.
Prior to the power failure, shared folders for scanning were configured using both methods listed above.
We cannot browse the network from the MPC2800 console.  Error message:  same as above.
All printers and workstations on the domain have static IPs.
No issues printing to the MPC2800.
The server can be pinged from the MPC2800 console.  Printer IP can be pinged from server.
The account used to authenticate the folder has full admin privileges.
MPC2800 uses SMB.

Any additional suggestions on how to troubleshoot or resolve this issue will be appreciated.  We are working around the issue by scanning to the workstations and copying to the server.
