I have a number of scripts that I use in Vista for manipulating my dev environment.  In some cases, these scripts require elevated permissions to execute properly.  Is there a way to

1. Detect from script that you are not executing in an environment with the appropriate permission
2. Automatically launch a new console requesting the elevated permission

I always operate in a least privelege environment, so I don't elevate permissions unless I really need to.  Unfortunately, I don't always remember which scripts/functions require elevation, so having the scripts help me automate this would be awesome.

I can't think of any other way than automating opening an elevated PSH console using AutoIT (www.autoitscript.com). Now, I've not played enough with Vista/2008 yet. Is there a basic command that will return a relevant error when trying to run it withouth the proper creds?
