Better leave these registry keys alone for ComputerName.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
ComputerName\ActiveComputerName
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
ComputerName\ComputerName
[[ComputerName (These keys contain information used only by the system and
should not be edited by users. Because these entries should be maintained
only by the system, they are not described in these files.) ]]
From...
REG: CurrentControlSet, PART 1
http://support.microsoft.com/default.aspx?scid=kb;en-us;102987
[[ComputerName
The names of the default and active computers, stored in two subkeys,
ComputerName and ActiveComputerName. To set the computer name, use the
Network option in Control Panel.]]
