Windows SBS 2003 and licensing

Max of 40 users in one location.
Does SBS take care of being the AD controller, DNS, DHCP, Print server, Exchange server, Fileserver, WSUS server...all on one machine???
Or can I spread these out over several machines? I'd like to keep Exchange on one server, fileserver on one, and also have a backup AD controller. The thought of all of this running on one server scares me! And having a backup AD controller would be nice.

If I seperate all these out:
Server01:  AD, DNS, DHCP
Server02:  BackupAD, print queues, WSUS, Symantec AV Corporate edition
Server03:  Fileserver
Server04:  Exchange
Licensing would be: ???
4 - Server licenses
20 - CAL's (20 included with servers)
40 - Exchange CAL's
40 - Licenses for Symantec

Am I overkilling this for only 40 users??? I just hate to put all my "eggs" in one server. And what about having a backup AD controller in SBS, is that legal? Using a Windows Server 2003 std. license??

Anyone have much experience, thoughts on SBS with 50 or less users?
Also looks like I'm limited to 75GB of Exchange data? Is that the same type of database the full-blown Ex uses, the .edb Seems it compresses pretty good so that a 50GB database translates into much more that 50GB of email boxes.

Yeah SBS would take care of everything.
I think for 40 users You can have exchange, AD,DNS and DHCp on the same server.May be have a another server as fileserver.
4 server I would say is an overkill. 75GB of mail storage would be toomuch for 40 users.Yeah you can use windows Server standard as an additional domain controller.
For setting up additional DC.
