DR error: Render host unknown (192.168.181.111) is not....

[silver]

i dont think its taht easy because in order to fix a possible network trafic problem we change our network to /1000 and we didnt have 10 machines, actaully just 7... so i dont think neither on nor other points are in trouble... it is really a big mistery, ... right now it is working perfectlly untill the next problem, unless a gigalan isnt enough for Dr render what else would be?

Just because you have only 7 machines that doesnt mean 10 connections are enough. They are eventually connecting to 1 machine for textures, to another for licenses (mind you even tho they dont need their own licenses, slaves still DO connect to the lic server) and various other things could be going on...mounted network drives etc. I would almost bet that this is exactly the problem.

but if this is the problem, what is really the advantage of DR systems? i ahve only 7 computers over here, i ahve friends with 60 computers... how are they suppose to work with Dr features? why there is a tool so powerfull but in other hand the windows cant offer support of it... thinking this way DR seems to be a useless toll because the system cant support more them 10 conections and we know that the main function of DR is to speed up the render process and how many machines we have, better for us. i jsut cant understand this ...

That has nothing to do with DR, but with Windows. And as far as i know there are workarounds for Vray's DR to work with more then 10 machines on a single workstation. But that does NOT account for maps/proxies/xrefs. A fileserver is a must anyways in my eyes...

a Windows server install on ur server machine would deal with this or a linux...

i believe that there is a top secret between the masters about the DR use, because we have been in trouble with it since the begining, and after changing for gigabit lan, change cable and change configurations, it insist in get fails in a while. i think would be interesting a manual about how is the best way to configurate DR in the network, what are the best brands to use what are cables, what are the way to share files, because... c'amon .. all of those things were already said and we try to folow them but the troubles insist.
now i get it to work sometimes and sometimes not, take a look at this image... 5 seconds before it was rendered with DR and everything went fine, why after a valid render i got this odd thing? is there any answer to this?

- I've found that starting a render, canceling it after a couple of seconds and then starting it again tends to end in a happy result. it doesn't solve the problem but is a quick fix.

- my only (noob) explanation is that the model doesn't reach out to the slaves in time before the rendering starts and that's probably why 2 scenes/materials get mixed.

@ instinct: sorry for the nitpicking but isn't it 15 concurrent connections?

[instinct]

nope, it's 10 (referring to Event ID 4226). And actually it is not a limit of established connections, but a connection-RATE-limit. Meaning there may not be more then 10 concurrent uncompleted connection attempts. There are also other limits, but this is the main one afaik.

Dont be fooled by "patchers" out there. They might help for some things. They dont help for a manager install. We tried patching the manager and it barely helped. Switching to 2k3 made most backburner issues we had disappear.
