HKEY_USERS question

[Dave]

When logged on to a 2000 or newer machine it is only possible to view the
default user and current user's key under HKEY_USERS.
We have a web based application that needs to write to the key for
IUSR_machinename but cannot due to permissions. Is it possible somehow to
display all user keys under HKEY_USERS.

Thanks
Dave

In REGEDT32 (not regedit), highlight HKEY_USERS, and on the File menu, Load Hive should be an available option. Click that and browse to the \Documents and Settings\IUSR_machinename folder, select ntuser.dat, click OK. It'll prompt to give it a display name, then you'll see it under HKEY_USERS.

I'm not sure if you can programmatically load a hive like that. I know reg.exe can do it from command-line/batch file.
