We purchased a white box (Intel Core2 duo with Intel motherboard) server from a local OEM who preinstalled Small Business Server 2003 R2. After finishing the setup, DHCP and DNS work well but AD seems to have some issues. We tried to "manually" join an XP Pro system to our business.local domain but get the message:
The following error occured attempting to join the domain "business.local"
The network path was not found.
The application event log on the server showed event 1030 and event 1058. We followed links on these events to Knowledge Base article 888943 about Group Policy, installed support tools, and used the ADSIedit.msi snapin. This showed us the gPCFileSysPath was correct.
