If you updated your Synology NAS to the latest 4.3.3776 then you will no longer be able to 'browse' NFS shares. NFS still works and shares can be added manually if you know the full path. Synology are aware of the issue, have been able to replicate it internally and have indicated that they may release a patch.

FYI, the NFS paths if you need to add them manually (assuming default volumes) are:

volume1/video
volume1/music
volume1/photo

Therefore full path would be displayed as nfs://xxx.xxx.xxx.xxx/volume1/video
