Deadline Remote control

Hi,
We have deadline setup but we are unable to get remote control/power management working. I can issue basic commands such as disable/enable, but shutdown related command don’t work. I have give both the users group and the individual user access to the command in the sudo file, along with allowing sudo as a service (disabling Defaults requiretty)
However when i go to shutdown/restart a machine i am greeted with this

could not resolve slave name (Phoenix) to IP address.  The machine may not exist on the network.

I have the hostnames setup in both the pulse hosts file, along with the local dns server, and all machines can resolve other machines by both hostname or ip without issue (ssh etc).

Aso each machine has W-O-L setup

[code] Supports Wake-on: pumbg
Wake-on: g/code]

But the machines dont respond to WOL, even though the pulse server seems to be working fine and setup correctly.

That is a really weird error, but I am thinking this is a DNS issue. Can I ask what major version number of Deadline you use? Can you go to one of the machines having this issue and open up the slave properties, then set the IP override for the machine and retry the problem commands?
