there's no need to change the distribution. The program "redhat-config-samba" is more than good enough for this purpose.
You'll have to recompile the kernel to get ntfs support though, nothing special. Check the Kernel HOWTO
for more Info on configuring the Kernel (redhat keeps its .config Files in /usr/src/linux-2.4/configs. Copy the right one out of this directory to "/usr/src/linux-2.4/.config" then go to /usr/src/linux-2.4 and use "make xconfig")
Please be advised: It is said to be pretty unsafe to enable read and write access to NTFS volumes (reading is fine - writing probably not). So be warned that you _might_ f*ck up your NTFS partition when writing on it.
Going on to the office PC:
I couldn't have expressed myself worse, sorry. What I meant was: Is the office PC somehow available via Internet or dial-up? If it's available via Internet, you'll need some sort of VPN tunnel. Maybe a simple terminal connection, secured by SSH, is enough, depends on what you need to do and the network at your office.
