Samba errors and very, very slow.

Hello all!!

Again Samba errors.

I have one server with samba and Linux CentOS 5,2 running remotely some applications fox pro and MS-Office on this server in some desktops this applications open very fast without problem but some desktops is very very very slow, after 10 minutes the application is open.

I tried install desktop directly on switch and in different ports to discard physical problem.
I tried format desktop and reinstall windows XP and nothing.
I tried enable port 139 on samba server and nothing.

What happen? My last solution format Linux Server e install Windows Server. :o(

Please I'm crazy with this problem!!!

Thank you.
If someone come to Brazil, I pay the beer... :o)
