Can't run smb on Drobo FS

For some odd reason smb has stopped working on the Drobo FS. The Drobo isn’t seen in any windows machine, no media players can use smb ( I have to use nfs with a PCH-C200), I can’t mount Public via smb with any Mac, etc… but the Drobo FS works perfectly with all my Mac’s using AFP.

Can I downgrade to 1.3 or anything that gives priority to smb? I realize this is not ideal, but for now I need to get smb working. I am afraid that resetting the Drobo with wipe out the drives.

Odd, most people I know have just plugged it in and it worked in a mixed environment. I changed the name from Drobo-FS to DroboFS. Could that have been the problem?
