Samba problems

[dln9]

machine A: Ubuntu 10.04 Lucid 32 bit

machine B: Ubuntu 12.04 32 bit

machine C: Linux Mint 13 Maya XFCE 4 32 bit


Up until a few weeks ago, I had samba running among all three of these machines just fine - either machine could access the other two. Then, for some unknown reason, it became VERY flaky and unreliable.

Now, sometimes a machine will be able to "see" one or both of the other two machines, but only sometimes. Most of the time a machine won't see either of the two other machines.

I can't figure out what to do about this.

Usually the problem is the machine A can't see either of the other two machines, but both machines B and C can see machine A - and each other - just fine.

Please, any help to fix this would be greatly appreciated.
