We have a problem on our Domain Controller running Windows Server 2003 R2. There is a problem with the time taking to write to disk and we think this is connected to the OS not reading the disks correctly. In Computer Management, Disk Management, it does not display NTFS, Healthy (System) etc and when you select Properties or Action, Rescan Disks it gives the error Disk Management, The operation was cancelled due to an internal error. There is nothing obvious in the Event Logs around the time this problem started to happen.
To me, it suggests a Windows problem rather than a hardware or RAID problem, although it could have been a RAID problem and the result of this problem is now being mirrored? We have a day planned when users will not be on the system, we are thinking of trying to Rescan Disks when server is running in Safe Mode without Networking?
Does anyone have any experience with this problem or have any suggestions as to how it was caused and how we can fix?
Any help would be very much appreciated.
Many thanks in advance.
