I've been administering my small SBS 2003 network for years. But at a "sophmoric" (with all that that entails!) level.
When adding a computer to the network, I've been EITHER:
doing so at the Server by right clicking on the Tree on "MyBusiness\computers\SBS computers" and then right clicking and selecting New, etc.
Doing so at the workstation, joining the Domain and providing the Credentials needed to add the computer.
I had thought that the two methods were effectively the same.
I now notice that 3 computers are listed in the windows described above, but 4 others are listed in MyDomain.local\Computers.
Does it matter? I have no group policies or other "stuff" that would affect all (to my knowledge). When on a workstation, I can "see" all the other workstations regardless or how they were joined.
I realize this is a broad question but ....
