Somehow this seems like a dumb question to ask, but after hours of Internet searching, I still am lost. With a Technet account, I can get all this software, so it is free for my evaluation usage. But why run special server software with home or small business? Have 4 PC's running all the time at home with Windows 7. Using Acronis for regular backups. Also 2 hard drives in RAID 1 configuration. Using one HTPC as the main server for storing data, including downloads and external HD's. All works well. What advantages are there to move from normal OS software in a PC as a server to specialized server software? Currently using MSE on each PC. Can not use that with WHS, but can still use it on clients. Have a similar setup at the office, with 5 PC's + dedicated PC as a server, all running WinXP and networked version of Peachtree Constuction version, as well as Symantec Client Security Corporate Edition. Again, all seems to be running great! Also running PCAnywhere and can access all home and office PC's from laptop when on the road. What am I missing out on?
