Ok, so I got my domain controller working running Windows 2000 Advanced Server. With 4 client machines running Windows 2000 Professional. The only problem is that my domain controller is set up on a different internet connection than that of the clients. I have roaming profiles set up on my network but when I try to login on the client machines it does ereything over the internet so it takes forever to logon and transfere files between the clients and the domain controller. Is there any way to fix this problem? Is there a way to force it to use NetBIOS or something so that it doesn't use TCP/IP to communicate with the server?
