Last week I pushed out windows updates to all our servers and clients, over the weekend the servers are set to restart if there are pending updates. All servers restarted fine apart from one, typically it is a fairly critical server. It seems to boot normally, even showing the cursor then waits for 30 seconds before just restarting. I havebooted in safe mode and it gets as far as crcdisk.sys then continues as before to show the cursor then restart. I have restarted to last known good configuration, makes no difference, exactly the same. I have attempted to use a restore point but the updates didn't create any so I don't have one.The updates I applied are KB971657, KB973507, KB970238, KB973346, KB971557, KB972260, KB968389, KB963678, KB961371, KB956744.I am using MS DaRT and I can see the data, event logs etc. but there are no events logged after the install of the patches. When I attempt to remove hotfixes they are not listed, presumably because the server hasn't completed its restart.Ideas anyone?

Check this: http://social.technet.microsoft.com/Forums/en-US/itprovistasetup/thread/3b98cd58-4e2f-48d6-9396-35a634fdcb6f How your disks are set up? I mean do you use RAID or not? Check BIOS setting fro your hard drives, try resetting BIOS to default. (memorize the settings, just in case)

There is a RAID controller on the server butthis server doesn't use it. I don't think the link you posted is really relevant to my problem as the server won't boot at all.Anything else?

You said there is a RAID controller but it is not in use, disable the RAID from the BIOS and try to booting the server.

This made no difference. Any other ideas anyone?
