I am setting up my small office (four people with XP machines) and am looking at various CRM sortware products. I am leaning toward ACT as I am most familier with it. My problem is the fact that it requires a lot of memory and my p to p wireless network can't handle it. Naturally I plan on changing to a client - server set up to solve that issue. I would like to run Debian on the server and use Samba (?)

My question is this: Can I keep the database on the server and access it from the Windows machines? ACT is a windows based program and works together with MS Office so I'm not sure how it will work. I've only played around with Linux as a hobby off and on for about five years and Debian since the release of Sarge so I'm not much more than a newby.

Alternatively, are there any good open source CRM solutions out there? We are a commercial financing and business consulting company that does a lot of different stuff so it have to be very flexible and easy to teach to employees.
