samba - Nov 2011 - dos/unix translating

I'm using server with Debian 6.0.3 + Samba 3.5.6 where I shared
"/temporary" folder.
It happens this behaviour: if I create a text file in my Windows XP client and I
copy it to /temporary folder, then I open it by VI editor into my Debian server
and I see '^M' at the end of every row.
How can I solve problem ? Problem references to Dos/Unix newline translating  ?
