I'm setting up SBS2003 standard and one of my client sites. The client machines have XP Pro running on Dell GX170s. I tried to add two machines to the domain yesterday through the connectcomputer setup and when I machines rebooted they could not find the domain. I ran the same process on my laptop, connected to the same switch and it all worked fine.
The PCs have access to the network, can get to the Internet and are having their DHCP request answered by the server. I've looked through the MS docs and have not found an answer.
