Stop Msg: C0000218 "Unknown Hard Error" When Registry is Overrun
The information in this article applies to:
Microsoft Windows NT Workstation 3.5
Microsoft Windows NT Server 3.5

This article was previously published under Q128254
SYMPTOMS
When you add users and groups to an Windows NT version 3.5 computer using User Manager you have the ability to overrun the registry with user and group information. When you reboot your computer, the following stop screen appears:

Stop 0xc0000218 (0xe11a30e8, 0x00000000, 0x000000000, 0x00000000)
Unknown Hard Error
CAUSE
User accounts and group information are stored in a secure location in the registry. By default, RSL (registry size limit) is 25% of the size of paged pool. The registry charges registry quota for its memory allocations. This is to prevent the registry from becoming too large for the available system resources. If a piece of registry is freed up, it is deallocated from the pool and the registry quota is returned. Although the space is still allocated in the file, there is no memory allocated, so no quota is charged.

If the registry becomes very fragmented, its file size may become much larger than the charged registry quota, potentially causing the registry to become larger than the system can accommodate at boot time. That is, the registry file cannot fit in memory in the available paged pool.
RESOLUTION
To address fragmentation, the Windows NT registry now continues to charge quota for portions of the registry that have been deallocated from pool, but are still allocated in the file. This prevents the size of the registry's files from exceeding the allowable registry quota, ensuring the file will fit in memory on the next reboot.

Additionally, a change was made that provides better coalescing of small portions of free registry memory into larger pieces when very large registry allocations are required.

With this change, instead of overrunning the registry with user and group information, when the registry reaches it's maximum allocation the following error message appears:

Not enough server storage to process this command

Err Msg: STOP: C0000218 ...Registry Cannot Load the Hive
The information in this article applies to:
Microsoft Windows NT Server 3.1
Microsoft Windows NT Workstation 3.1

This article was previously published under Q104203
SYMPTOMS
When you install Windows NT or Windows NT Advanced Server from a CD to a machine whose C drive is a SCSI drive with a DTC3290 SCSI controller, Setup may fail, displaying the STOP message:

STOP: c0000218 {Registry File Failure}
The registry cannot load the hive (file):
\SystemRoot\System32\Config\SOFTWARE
or its log or alternate.
It is corrupt, absent, or not writeable.
CAUSE
During the installation process, Windows NT expects to read certain information from the SOFTWARE registry hive. Due to a hardware problem, this cannot be done.
RESOLUTION
This problem was not reproducible at Microsoft. If you run into this problem, the following steps may help:

Use only hardware listed on the hardware compatibility list (HCL).
Ensure that the SCSI bus is properly terminated at both ends.
Try a different SCSI cable.
DTC has a firmware upgrade that fixes certain over-run problems
