Some render hosts don't contribute

I have 6 computers that usually contribute as render nodes but only 3 are working since a few days.
I get the in the V-Ray progress window:

Why are some nodes "added to waiting list" ? I can't find a setting I changed that would have an incidence on this...

I started to have same problem on my 2 PC´s. File sharing in enabled, I can access computers from each other. Tried to run Spawner as administrator as well. No help.
