workgroup formation policy

I am current trying to network about a hundred systems. is it advisable for me to put all the systems in one workgroup or split them into odifferent workgroups. merits and demerits are expected from the honorable members of this forum. what is the effect is a particular computer is part of more than one workgroup in thesame LAN .

thanks

Is this going to be a Windows-based network? If so, I would suggest setting up a domain and use Active Directory instead of a workgroup environment...

Microsoft recommend a domain structure when you have more than ten machines if I remeber those old courses correctly

That sounds accruate.
