[Networker] "! no output" error message

Hi, 

I have a little backup group of 3 machines (behind a Checkpoint NG FP3 
Firewall) that were backuping well for some time.... Last tuesday we did a 
manual backup from one of these servers, swaped the server with another 
one (same config, including legato passwords and version) and successfully 
recovered the data that was manually backuped previously. Since then, my 
nightly full backups stop working. All the servers in this group have this 
error: 

server_name : D:\ : !no output

I tried opening all the ports, no luck. Recreating the client object, 
didn't work. Inscreasing the retries and timeout values, nothing. Moving 
server to another group, nope ! And of course I rebooted the server. 

I checked the Networker docs and did what they said (mminfo to check if 
the data is backuped [it is not], there's plenty of free disk space on the 
server, ports are opened...etc..)

I'm all out of ideas here... Somebody throw me a rope, please ! ;)

Networker system setup : 
Compaq Proliant 1600 + 5 compaq dlt drives + Windows NT4 SP6 + Legato 
Networker 5.7

Thanks a lot !
