Should I Use Homegroup in a Small Office?

I have a small office with 3 PCs, 2 printers and 2 scanners. I am in the process of replacing the PCs with new machines, all running Windows 7 Professional. Should I be using the Homegroups function as the basis for the network?

I need to have some differing folder and file permissions on the various PCs and user accounts, but nothing too elaborate. I also want to ensure that whatever network I put in place can handle the addition of 1 or 2 more PCs over the next 2 or 3 years.

I used Homegroups in my home network and was very happy with the ease of set up. It has also functioned well with no problems whatsoever. With limited technical capacity amongst me and my staff, I really need to keep things simple and well functioning in my office - without the need for significant maintenance.

I am a bit confused as Homegroup is obviously focussed very much on home networks. However, is there a compelling reason not to also use it in a small business such as mine? If there are such reasons, what are they, and what should I be using instead?

I would very much appreaciate some guidance on this. Thanks.

Well I actually have a server built into my house... I use the homegroup function.

The only thing different is that I only enable the server folders for homegroup and leave the rest of the computers disabled.

It does make it it easier but I also do have workgroup enabled. I still trust my Ipv4

It is all about how you feel about it and your opinion.
