Comment 19 for bug 982316

Have had this issue for a while and believe it started for me when updating to 12.10.
Have been mucking around a lot this morning and when making coffee it just started to work again.
Not sure what is the root cause is yet but have done the following.
I started with the theory that the fact I cannot browse via SMB to my NAS is the problem.
- I installed cifs-utils
- I edited /etc/samba/smb.conf. Here I changed the 'WORKGROUP' to a friendly name and I changed the search order to start with bcast.
- I edited /etc/nsswitch.conf to include wins
- I disabled GUFW
- I have long had this issue with Avahi (http://avahi.org/wiki/AvahiAndUnicastDotLocal). I changed the domain name here to the friendly workgroup name from smb.conf.
(These ideas from http://ubuntuforums.org/showthread.php?t=1169149)
-I have an old script that mount my NAS share via gfvs command that runs at logon. The backup now running is against one of these shares.
-I manually mounted another share via mount.cifs
- Have tried to understand the authentication issues I seem to have with SMB by following BAB1s advice looking at smbclient -d3

Somewhere in this mess lies my answer as it is now running again. I will write more when / if I find the culprit
