Is there a kernel version of GetComputerName()?

secLookupAccountName() doesn’t seem to work correctly if you don’t preface the account name in question with the local machine name…

Not sure but GetComputerName just reads it from the registry so why not do
the same?

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ComputerName\ActiveComputerName

Thanks. Why ActveComputerName vs ComputerName?
I take it you have access to source code?

I wish. It would make my life much easier.

But when you change the computer name the ComputerName field is updated but
the ActiveComputerName field is not until the system restarts. A computer
name change doesn’t take effect until the system restarts but most of the
registry values are updated before that happens. I guess
ActiveComputerName is there for book keeping purpose so other components
can query the original name after a change occurs.
