DR works from the WorkingStation but not from Backburner

[Arnaud_3DMS]

I explain in details :

I work with my workingstation and a using local renderfarm of 6 machines.

I've got a licence for my working station + 6 render nodes.

i said to all the render nodes to get the licence on my workingstation

When i launch a rendering with backburner, only the machine of the server of the backburner is rendering no the others...
When local render on my working station, all the nodes of all the the render farm are used...

So here the BECAUSE :

i had not checked the save servers in the scene...
Now it is checked,it works.
If someone have another solution, i check.

MAX 19.0 SP2 commercial
V-RAY Adv 3.40.03

we have a renderfarm of 6 machines :

01-02-03-04-05-06

The vray licences are found on each machine configured as 3smax slave machine :

I tested the DR rendering on the renderfarm 01 = ok
I tested the DR rendering on the renderfarm 02 = ok
I tested the DR rendering on the renderfarm 03 = ok
I tested the DR rendering on the renderfarm 04 = ok
I tested the DR rendering on the renderfarm 05 = ok
I tested the DR rendering on the renderfarm 06 = ok

ok but, Only the machine on which the server is launched, is computing...


If I launch the DR rendering of the same scene on my workingstation (on which the dongle with the licences is installed), all the machine are calculating.

i want to launch the rendering on the 01 and that all the node machine compute.

Help !
