Try it and see - seriously! :-)
I don't know what is involved with your "Mac server", but with a Mac running OS X 10.4.3 (Tiger), I go into "System Preferences > Sharing" and enable (a) Personal File Sharing and (b) Windows Sharing which lets me access the files in my "Home" folder. You probably have a more complex set of options but the basic principle may be essentially the same.
As with Windows to Windows networking, the computers need to be in the same "Workgroup". In the Mac, the Workgroup name is set up in:
Applications > Utilities > Directory Access
where SMB/CIFS is ticked and then the Configure button clicked.
Now this assumes that you are running Peer-to-Peer networks similar to those used in home networking. If you are using Client/Server networking in conjunction with dedicated server software then the situation is probably very much more complex and certainly beyond my knowledge.
