It's a possibility - but the two machines which were exhibiting the fault are in Slough and Baton Rouge respectively, so under very diferent cliatic conditions. Howevere, something, has chhnaged to make it stop locking up! The USA one was doing it every couple of hours at the start of the week, and the UK on wouldnt last more than half an hour at one point. > Alternatively, could it be that the workload changed very slightly -- you're > doing less DNS queries, or the network latency to the DNS server changed?

My iiLO2 appears to have the ability to generate an NMI oon demand, so that could be used if/whhen the fault crops up again. thanks, will let this lie for now and resurrect the thread when I can get some more useful data. -pete.
