Searching most simple local setup

Hello,

in the past I always used a CVS server setup by some other admins.

Now I need a local CVS installation (for Windows).

I already downloaded v.1.11.22.

How can start this CVS server in the simplest way?

All stuff should be stored in the subdirectory "xdata" of the directory where cvs.exe is currently 
located.

Do I have to open some specific ports in the local firewall for successful running?

Thank you
Ben
