Current set up is Standalone windows 2000 server also running ex5.5. Small
organisation of only 7 users.

The desired solution is to migrate to Windows 2003 server standalone running
ex2003. I am aware of the migration paths using the swing methods and have
servers available to introduce to the domain to perfrom this.

The question is Is there a way of upgrading this client to use SBS 2003 and
is this a better option?? If so how can this be done since SBS will allow
only one server in the domain (exchange)
