A Tale of Two Laptops:
I have an Acer notebook running Linux Mint with Samba.
I also have a HP dv6 that dual boots Win7 and Ubuntu 12.04.
On the HP, while in Windows, the network is doing just fine, I can see all the folders that are marked to share. The issue is when I am in 12.04. What is strange is that works sometimes, but not others, but as of late, trying to connect to my server just causes the Browse Network to become unresponsive and require a force quit.

I've looked for solutions, but every thing that pops up once you mention Samba and Ubuntu in a search is about Windows issues, which I don't have.

Thanks for any assistance,
