I would like to run one Domain with Windows Server 2003 for 30-40 small companies (3-10 computers). To have one domain (company.local) and give all the companies access to domain services (Printers, Folder REdirection, Remote Access, DNS, DHCP, SharePoint ...). All the companies would be located in one bussines buliding, so there is no need to create Site (or I'm maybe wrong?) and I have only one server. There is no need to have more than one, becouse all the companies together would have cca. 100 employees.
There is one more "wish": Only the computers in the same company can see ich other, so that computer from company A can not see the computers from company B.
Is all this possible to do with AD design? Any suggestion? Please. ;-)
If not, please give me a hint how to solve this task'
Thanks a lot to all!!!
