Great; I hope you understand why this is working :-))
Another remark, don't do this...
private const int LOGON32_LOGON_INTERACTIVE = 9;
LOGON32_LOGON_INTERACTIVE is 3 and carved in stone....
change the declaration into:
private const int LOGON32_LOGON_NEW_CREDENTIALS = 9;
and stay good friends with those who have to maintain this code.
Willy.
