deleted, entries are added to the registry by the plug-and-play manager, potentially causing the registry
to grow beyond the allowed capacity.
If more than 700 entries are in the registry, the next time the system reboots, the following error message
appears: Failed to load Windows 2000 due to a file missing or corrupt in the
\WINNT\SYSTEM32\CONFIG\SYSTEM directory.
Refer to the Microsoft Knowledge Base article (Q269075), for more information about the registry
growth problem.

The Device Manager may show the device with a yellow warning icon on it. A reboot of the system
removes the device.
Windows 2000 dynamic disk snapshots and snapclones
The use of snapshots and snapclones in HP SANs is not supported in a Windows 2000 environment if
the snapshot or snapclone is presented to the same Windows 2000 host as the LUN from which the
snapshot or snapclone was created. Snapshot and snapclone are features of the HSG80 and HSV110
controller-based HP storage systems. All dynamic disks on a system have information in their metadata
about the other dynamic disks that exist on the system. When Windows is presented with two dynamic
disks that have the same information on them, it cannot resolve the conflict.
