Hi rmoore!
I would love to hear that Buffalo tech team called you and provided a working solution, 'cause I've gone through it earlier this year and never got it joined! They didn't hang up on me but stucked on saying:
Maybe your GPO's are the problem. So I asked which GPO has to be set set up how to let the Terastation Pro II join the AD (SBS 2003), but I only get the answer, they do no Windows support...
I've tried recently with the newest firmware (1.27.117 --> http://downloads.buffalotech.com/TS-HTGL_FW127-117.zip ) but wasn't successful, so I tested it with the external SMB Server authentication and created about twelve "external" users, it seems to work from most workstations. Unfortunately I want to backup directly from the Windows Small Business Server 2003 to the NAS, but that simply doesn't work 'cause this is also the external SMB-Server. Back to square one!
I not very satisfied with my "solution": I turned of authentication for the backup-share and just made it hidden, rebooted the terastation pro II and I could use it.
Funny, though I bought this model mainly of it's integration into AD!
Any hint appreciated, thanks in advance
