On the other hand, if you were to connect the other clients using Connect, install AC on the Essentials machine, you would have a domain network.
FYI: With Essentials, you don't use Exchange. You basically have Exchange in the cloud. You subscribe to Microsoft Office 360, and everyone has Word, Excel, Powerpoint and Exchange. Some versions come with SharePoint that dreaded program, which remains clouded in secrecy, lol.
Tom, this was the way Microsoft was trying to get people legal. Not many people can license Microsoft Office Professional Licenses up front. $300-400 per computer.
SBS Essentials is all about the Cloud while Standard is about on-site. Obviously on-site will be more work. I avoid cloud-based solutions if possible. One of the main reasons, we went with AC over other EMRs. Things tend to cancel out when you have to pay $400 a month to have a reliable internet connection. Then there's the monthly subscription costs which is often licensed per user. For larger corporations, it's a no brainer to go with an onsite solution vs a cloud-based ones. (Bandwith, licensing, etc.) Without internet, a cloud-based business would stop. While the hosting companies rarely go down, your connection is more likely to go down. I'd hate to close the office just because Roadruner wasn't working. Which you would have to do if you were using something like AC's hosted services.
Basically, get Standard if you want on-site Exchange and/or have more than 25 users.
Acrobat does the same with its $400 professional license. They really need to dial down the prices.
Ebay is your friend when trying to get these pieces of software. I scored a copy of Acrobat Pro for $180 last week. Almost paid $400 on Amazon.
