Then the *other* piece of software running on the computer wouldn't be 
able to log audit events under the correct username.

Under Windows, any processes started by a user ordinarily get terminated 
when that user logs off. Unless they do something special to prevent this...

Why not?  If it can log them under the correct username when nobody is 
logged on, why shouldn't it be able to do it when someone else is logged on?

Like what? Do most programs cope OK with running when nobody is logged on? 
I would have thought some get a bit screwed up what with there being no 
desktop or whatever.

The program continues to run with nobody logged on, and continues to 
execute any instructions it has been given. However, to give it 
instructions, you have to log on, and it records the username of the 
person giving the instructions. If we had a single logon, there would be 
no record of who issued those instructions.

No, I meant unless the *program* does something special to tell the OS 
it wants to keep running.

It sounds like the guys at HQ are looking at trying to run our problem 
software as a service somehow... We'll see if they can actually get it 
to work. (I rather suspect not.)

Just set it up so the program that you give commands to cannot be started as 
the lab user, and then do "Run As" the real user when you need to issue 
commands...

BTW I thought you could switch users on XP and Vista without the first 
user's programs being shut down.

That could work, I guess.

Uh... yeah, possibly.

You do know you can have two people logged on at the same time, yes?

Start program one, lock the screen, log in as second user, start program 
two, lock the screen.

Actually, that might be slightly harder with AD. You might have to log in 
remotely to have multiple accounts logged in at once.

In Windows XP, you cannot "switch users" like that if the computer is part
of a Windows domain. But it is supported since Vista.

Is that true even if you log in remotely with RDP? I know we did that with 
Win2000, so I find it hard to believe XP can't?

Windows XP Professional supports 1 user logging in via RDP (but only if 
nobody is logged in remotely). Windows 2003 Server supports multiple RDP 
sessions, but Windows XP supports only one at a time. As in, before 
anybody else can connect, you must disconnect (i.e., log out).
