I'm pretty sure that the message about the installation being interrupted is purely cosmetic - in other words it does not mean that there was actually any problems during the install. If a BESTART on the NetWare server works ok and if NDMPD.NLM is loaded then all should be ok.
Do you see your NetWare server under Remote Selections-->NetWare Agents? If not, check that name resolution is working in BOTH directions. Can you ping by server name both ways? If not, try updating the hosts files on both servers and then try again.
You may also need to add the NetWare server to Tools-->Options-->NetWare SMS (remove the '*').
