Small office best practices

I’m setting up a network in a small office of 10 users. I will be setting up a Windows 2003 domain with AD. Users will need access to the Internet and will likewise be connecting remotely from their homes, hotels, etc. There’s currently a Linksys wireless router in the office that issues out IP addresses via DHCP. Would it be better to leave DHCP on the router or use the Win2k3 server to do this? What are the pros and cons with each setup?

Thanks in advance for anyone’s input on this.
