I work for a business that has smaller companies (1-3 computers each) under its roof, for a total of 12-15 computers in all. With this came multiple servers from previous business locations. I am trying to get rid of a couple servers and consolidate everything to a pre-existing workgroup. In doing so I will be removing a couple servers that were previous set up with domains. This won't be the case any longer. One centralized storage location functioning as a workgroup.
My question is what would you suggest I do to set up the file sharing so that each business can still specifically have access to only their necessary files. I was thinking of setting up a user account for each business on the central workgroup and then they would use that user : pass to log in from each respective computer. But upon doing so, I haven't been able to log in. Sometimes I will get a pop-up asking for a user name and pass, which will or will not work. Sometimes I get an error message not allowing me access and to contact admin.
Any input is appreciated. Thanks for the help.
