I'm doing a network for a small business. All the computers are on a domain and the domain controller is running on the server. I'm also trying to setup Active Directory so that users can login to their account at any of the six workstations in the building. However, for some reason I'm only getting ~46kb/s transfer rates across the network which is obviously pathetic. Consequently, Active Directory is impossible to do right now as there is no way to sync large amounts of files with such a slow transfer speed. I've included in the image below a rough sketch of how the network is laid out. Do any of you have any ideas as to why everything is going so slow?
