Re: Primary group

Hi Andrei,

Thanks for your feedback.

Since we normally ignore the Primary Group field in Windows, there are not
much tools with the function of setting this field. As I know, the
pview.exe from NT4 resource kit may provide this function, but it seems
that I can not install it on my Win2003 SP2 machine:

Actually, it is not hard to write a small program to set Primary Group
field. You may first call OpenProcess with OpenProcessToken to obtain the
security token. Then you may call SetTokenInformation with
TokenPrimaryGroup.

Finally, I am curious that why do you want to manipulate the
TokenPrimaryGroup field. Do you play with the posix subsystem on Windows?

Jeffrey Tan
