This used to work our Novell 4.10 server. I've tried Arcserve's tips for this error except for "check routers and other hardware problems". set timeout params to the max in spxconfg. Yes I'm using 512 Kbyte packets to communicate with WS Agent. There is no network broadcast message blocking the station. I can select drives to backup but the above error kicks in a few seconds, every time. [sig][/sig]
