13.04 Not able to browse network shares

[Dave H]

just completed a distribution upgrade from Ubuntu 12.10 to 13.04. I am no-longer able to browse my network shares on my NAS unit as previously able to on 12.10. When accessing "windows Network" I get the error window:
Unable to access location
Failed to retrieve share list from server: No such file or directory

I dual boot Xubuntu 12.10 and confirm I am still able to access all network shares as I did with Ubuntu 12.10. If I run findsmb in Xubuntu 12.10 I get:

                                *=DMB
                                +=LMB
IP ADDR NETBIOS NAME WORKGROUP/OS/VERSION
---------------------------------------------------------------------
192.168.0.6 QNAPNAS1 [NAS] [Unix] [Samba 3.5.2]

If I run findsmb in Ubuntu 13.04 I get:

dave@ENVY6:~$ findsmb

                                *=DMB
                                +=LMB
IP ADDR NETBIOS NAME WORKGROUP/OS/VERSION

Sorry not a bug, further investigation found NFS support was missing, installed nfs-kernal-server package and I can now map my NAS network shares. Not sure if I should be able to browse network shares or not using Files/Nautilus.
