Hello,

Would 'runas' suit your needs? open a command wnidow, and type runas for
syntax.

Regs,
Tim

Subject: Windows,Linux, admin account's, su,runas, and user switching


I just recently started running as a non-admin on my windows 2000 pro
home machine.

The main reason I had put this off for so long is because it is a PAIN
on windows to run as anything but admin !

Though runas alleviates a lot of problems, it is a pain in the butt
to enter your pass everytime you need to run a system program.

Of course, I know this is the whole point !

Linux has su which "caches" your credentials for a while ... a very
nice feature.

Windows XP has user switching, but I had heard user switching somehow
weakens the system security ?
Is this true at all ?

I have come up with my own solution to this ...
which i hope is a nice compromise between security and convenience.

I LOVE this program Total Commander. Now I have it set up as a sort of
"mini Admin shell". I launch all the programs i need to run as admin
from it, like control panel, services and other admin tools, nero, etc
... I have Total Comm. itself setup with "runas different user" .

The main risk of running as admin is that you may inadvertently run some
mailicious code under admin privaleges.
So I should be safe having this "mini admin shell" running in the
background ... since only programs i launch from it will have root
privaleges ?

Any thought's on this welcome.

p.s.
If anyone wants to comment on the effectiveness of the windows GINA
(screen lockout mechanism) I'd like to hear opinions on that too.

cheers,
e
