you are actualy using forms authentication. So setting identity imeprsonate=
true causes your app to runa as IUSR_..... (because this is anonymous IIS
account). identoty imeprsonate... must be set in web.config (it is not there
by default). If you would use authentication = windows, then your current
account would be used for logon and your application would run in that
context .
You are not seeing security tab probably because:
a) you are not administrator
b) your partition is formated as FAT32. Convert it to ntfs by running
convert c: /fs:ntfs
