NetWare DS backup problems

We have been having problems with the backup of the NDS to ADSM.

The server is running NW4.10, with the latest patches applied, and the
client 2.1.0.5.

Before we applied PTF 5 it looks as though the backup of Directory
Services may have been failing altogether.

ADSM seems to be trying to backup non-existant objects in the NDS
which then produce failures.

If anyone has had similar experiences and managed to find a solution,
then we would be very grateful for your assistance.

The message below is part of an email dialogue that has been taking
place "in-house" regarding the situation:
