Default WMI EnableStatic not work in Vista
I have a function to switch network from DHCP to static, the function works
fine in XP but not work in Vista, the return is 0 = no error, but there is
nothing changed in Vista, any help are welcome, I am using VS.net 2003 +
latest SDK
Thanks!

John:
Is UAC = "User Account Control"? I don't know how to completly disabling it,
I tried to use "secpol.msc" to diable all options, but no help.
Please give me some detail if I did not understand what you said.
Thanks!

User Account Control.
