LinuxQuestions.org - Viewing Windows files on Red Hat / Hotmail PSM Problem

I have a Windows 2000 Professional machine (Sever1), which is networked with another Windows 2000 Professional (WK1) and a Red Hat 9 machine (WK2).

Server 1 is configured with Verizon DSL with a router. WK1 is able to access the Internet through a wireless NIC and WK2 (the Red Hat) is wired to the router and both WK1 and WK2 can access the Internet without problems.

Can you help with these two issues:

Since this is a home testing environment, although I would like to hear and read about all solutions, I will also like to know solutions, which will cost no money.
1. How can I see the files on the Linux machine from Server1 and from WK1?
2. How can I see the files on Server1 and WK1 from the Linux machine (WK2)?

3. Also on the Linux box (WK2), when I try to log on to Hotmail.com I get the following message and I will appreciate hints on the solution:
”…. You need Personal Security Manager (PSM ) …. “

Is this specific to Red Hat? I never had to install this on the Windows side to log on to Hotmail? Any links to the download and installation instructions will be appreciated.

Thanks.
