Thanks Guys
To answer Thelad's question both servers are running netware 4.11, both have tsands, and tsa410 loaded, but I don't know if this has enabled sms.
Mark I am using the enterprise version of arcserve and as far as I can tell it is using tsa to copy. The error that I have been receiving is cannot login to 4.z tsa with user supervisor, I read up on this and the recommendation was to create another account with the same rights level, whcih I did and still no luck. I hate to sound ignorant, but could you explain how to do this trace on the packets, as the only debug trace I know of is for tracing errors with the NDS.
