Network

i need to put in place my client/server network.
for example,my domain is EFA that i implement on PC win server 2003.i have those end-users in Marketing( Manager,assistant manager,PC1…),ITdepartment(manager,Assistant Manager,…),Administration(Managing director,director,…).
this is my plan.
so in my network places can i see those pc’s in each workgroup such as what i designed on top?
in domain EFA i open and see Marketing,ITdepartment and Administration.
N.B:using one domain controller.
