Server 2008 R2 BSOD c000021a Fatal System Error
Cannot get a Dell Power Edge T110 to boot after a single disc failed in a RAID 1 Config on Perc S100 Controller. Disk replaced and rebuild in RAID.
I've spent hours online reading, done the following:
Memtests and Disk Hardware Tests
Tried to Boot in Safemode, loads to storport.sys and then reboots
From the command prompt Run CHKDSK C: /F
Run SFC /SCANNOW /OFFBOOTDIR=C:\ /OFFWINDIR=C:\WINDOWS
boot using Last Known Good Configuration
bootrec /RebuildBcd
bootrec /FixMbr
bootrec /FixBoot
renamed c::\boot\bcd bcd.old
Recovered Registry from Regback in c:\Windows\System32\config
I have marked the partition as Active in DiskPart
Disabled Driver Signature Enforcement in Advance Boot Options
The BSOD is get says the following:
STOP: c000021a {Fatal SyStem Error}
The verification of a knownDLL failed. system process terminated unexpectedly with a status of 0xc000012f (0x00086e00 0x000000000)
The system has been shut down.

Sounds like the controller for the hard drive driver is corrupt. get driver files and use a hirens disk to get to a prompt where you can copy the drivers to the server's hdd. If you don't have a good backup of the drive I would clone the driver before attempting any repairs.

Thank you I have started the download of the Hirens disk. Just want to confirm, I should copy the controller drivers (bcraid.sys) files to the c:\windows\system32\driver
I'll clone the drive before attempting this.

could you please do this once :
Load system registry once again and remove all entry from the below key except default one
HKEY_LOCAL_MACHINE\TEST\Co
faulty system registry key is loaded as test
Also check for the automount key from the below location
HKEY_LOCAL_MACHINE\Test\Co
It should not be in disabled state
after that boot the system.
take backup of registry :-)

Also let me know if memorydump is generated for this.

Okay, after that you have to load the faulty machine system registry and when it asked to provide name you have to give any name I given test and that was the test indicated.
