samba - Oct 2002 - Files are showing up as hidden when view from windows...

I have a string occurance one one machine.

We have a Solaris 2.6 machine, running Samba 2.2.4.

When going through the files from my Win2000 SP3 machine, I see some files
are showing up as hidden. When I copy them over to my machine, they stay
marked as hidden files. I can't figure out what is making  it think these
files are hidden. They don't have a . prefix or anything.

Any clues?
