Wotcha folks - am having issues with a pile of iMacs and wondered if any of you could shed some light.
We have 16x iMac 20", 4Gb Ram, 250Gb Hitachi HDDs, Core2Duo 2.6Ghz (iirc) and an X-Server.
The iMacs are authenticated to ActiveDirectory, with accounts managed by the X-Server. When users logon, OSX creates a local folder structure for each user (based on the template I created, which is nothing special). It also maps their Windows roaming home folder, and any necessary shares of our Win2k3 servers.
So far, I've had to reinstall at least 5x of these iMacs as they bluescreen on poweron, at random, for no apparent reason.
Single User mode > fsck -fy makes little difference (altho does repair a pile of fs issues apparently succesfully) - generally leaves me at the spinning bootup logo after it's been run rather than bluescreen, but will go no further. Only solution is to redo a Netinstall off the X-Server.
At the moment we're considering splitting them from AD to see if that resolves the issue, but that knackers up multi-purpose useage by other departments (these are in the Music Dept, running Garageband and Cubase 4).
I've also disabled all power management as have spotted posts on other forums regarding bluescreening being related to waking from sleep mode.
Has anyone else experienced a similar issue with these latest iMacs under similar circumstances?
I can't go 48 hrs before there's another one that needs sorting at the moment...

Presumably you built one of the iMacs, imaged it and built the nbi to be pushed out by the NetBoot Service?
The error log may refer to the LKDC being the same? Essentially all the iMacs think they are being authenticated to themselves locally using the same Local Key Distribution Centre. This is in addition to and separate from AD's KDC.
The 10.5.6 Combo Update (Server) is supposed to fix this. Apple have posted a kbase article with more information.
