317012 INFO: Process and Request Identity in ASP.NET
: Microsoft does not recommend that you set the ASP.NET worker process to run as the SYSTEM account or as an Administrator account. If malicious code is somehow executed under ASP.NET, that code can do more damage if the code runs under a highly privileged account such as the SYSTEM account or an Administrator account.
