Over the last week or so, my Windows 7 desktop has intermittently had problems connecting to atomtux. While accessing atomtux via Firefox worked, the Windows file sharing component refused to connect. Occasionally, performing a system restore would fix the issue. However, sometimes it did not help. After a little searching, it looks like the problem was that atomtux’s clock was ahead of my desktop’s (by about 10 minutes). After getting my desktop’s clock back on track (it was falling behind as atomtux synchronizes daily) it once again could access network shares from atomtux.
The moral of the story, if Windows won’t connect to a network share, check your clocks.
