Checking computer user

[elenev]

Hi,

I am writing an intranet application that should only be accesible by administrators. I want to check whether the current user is a member of the Administrators group and then give him access.

I know I could use WHO or WHOAMI in UNIX but I am developing for Win2000 and IIS4.0

Any ideas on how I can do this?

Thanks a lot.
