Server is NT, running ADSM 3.2.20.
Clients are Novell (7 of them) , UNIX (15 of them) and NT (25 of them and
growing) running ADSM 3.1.0.6.
The network is 100 MBit direct via switched Ethernet.

Randomly the NT Server clients stop with a:
ANR0480W Session 10742 for node XXX (WinNT) terminated - connection with
client severed.
Once this happens, the only cure is to stop and re-start the schedule
service on these clients - and then it runs OK on that server for a number
of nights. From the 25 NT clients we get 2 or 3 of these connection severed
a night.

Does anyone have any ideas that we can try in order to remove these errors
and to keep the clients running??

We have checked:
  network - nothing special happening
  times - any time at night
  NT servers - it can happen to any server - although there may be a
tendency to ones that have only been added to ADSM in the past month.
  data - servers can vary from 2 GBytes up to 20 GBytes.
  ADSM Agents - the only servers that do NOT get the connection severed are
the Exchange servers.
