Summary	0000697: IsAdmin check in sfextra needs more tweaking..
Description	Had some trouble getting SpeedFan to install on my vaio, tracked it down to the IsAdmin() check. The code calls GetTokenInformation only once and it fails with an invalid buffer size. There is a previous report of this where the buffer was 1024 bytes, the fix seems to have changed the size to 4096 bytes. The best way to use this method is to call once with a NULL buffer and 0 bytes buffer length, then allocate a buffer the size of the value returned in the return length dword you passed, then make the call again passing that allocated buffer. You can't really make a guess at the number of groups a token can be a member of, so it's easiest just to use this method. I was able to get the product to install by working around the issue in the debugger, but a fix for this would be appreciated.
Steps To Reproduce	Install Vista, run speedfan installer using a domain account. Possibly easier to just create several generic security groups in compmgmt.msc and then create an account that is a member of all of them.
