Hi Paul. Thanks for the quick response. I didn't get back into the office on Friday after posting my question and came in Monday morning to find all the Sunrays down! The problem (sorry I should have mentioned it to begin with) is that from time to time a few of the Sunray's lose connection, and drop out with a 21 error code. The dhcp server is still running though. I see a lot of errors like Worker7 NOTICE: readMessage::socket looping limit exceeded.Close it. and Network: TCBDaemon: packet receive error in the /var/opt/SUNWut/log/messages file. This happens a few times per day and has been going on for a few weeks. When they all went down like this this morning, I checked out the dhcp config with dhcpmgr and it reported "Internal error" and showed no addresses at all. The same for "pntadm -P". I removed the SUNWbinfiles file for our network from /var/dhcp and recreated the IP adresses. It's working (for now at least!). I'm not really sure what happened. It seems as though the file was corrupted, but I have no idea why! So my concern now is will this problem reoccur and what (if any) is the link between the intermittent dropouts and the total crash. > > What you can do, is setup different switches for groups of 20 sunrays, > and have the 3 nics serving 3 groups of 20 machines.

That may happen some time in the future. I don't think we have the extra switches for this. The configuration at the moment is using LAN connections and not per-interface configuration. There is only one IP address listed for the authserver though.

I'm fairly new to Solaris (I've managed the odd box in amongst my Linux systems) and Sunrays are completely new to me. I've only just started this job so I didn't want to go changing software until I'm a bit more familair with the setup.
