Remote Access that allows a second log in while in use?

[Velvis]

I have a client who has machines that are in use 24/7 for access to a medical system over the internet.
It is difficult to find a time when the machines are not in use.

Is there a remote solution that would allow remote access that wouldn't interrupt the end user and they could continue to work?

Terminal services or citrix on windows server.
I don't know of any non-unix type systems that allow a second session on a workstation.

I think there were some hacks at one time that allowed it on XP.

EDIT: Apparently you could do it on XP once upon a time but the feature was removed. there are hax available.

The machines are XP Pro. Anyone have any links to the hacks?

[ljtechservices]

that might be against the rule to link to those.

Yeah, and break several EULA's whilst your at it.
I would've called it a work-around, instead of hax :p

Kaseya IT toolkit will give you access to the command line while someone is logged on if that helps

will powershell do the same thing?
