I've got 5 pcs (2 winXP Pro, 3 win XP Home) that I have always run as a workgroup. All talk via wifi to a Linksys router, then DSL, then the internet. Because I'm a programmer, and I need to work with Exchange Server, I plan to reformat PC#1 as a SBS2003 box. I have MSDN Universal.
1. Can Win XP Home boxes be part of a SBS 2003 domain? If not, How can I install upgrade from Home to Pro without losing all my installed apps.?
2. Are domains and workgroups mutually exclusive as far as any one PC is concerned? I want all 5 pc's to be be able to network together with minimum hassle (workgroup), but I need at least Exchange and one client PC some of the time (domain)
3. If I change over to domain, do I have to turn on both the server PC and my main notebook just to get email?
4. Can I/should I reinstall Zone Alarm Pro, CA Anti Virus and Webroot Spy sweeper on the new SBS 2003 install?
