Would the fact that the PC is a member of a domain and the fact that the user accounts aren't locale to the system in question be the reason why the locally logged on user is getting disconnected?

Being an administrator of a around 30 PCs on a network, this feature would be extremely handy rather than having to kick users off their Windows XP Pro PCs so I can check things or run aduit software.

So, question is, does this hack/method work when the PC is in a domain? Has anyone got it to work on a PC in a domain?

It won't work on domain PC's because you need Fast User Switching and the Welcome Screen. Check this post out -

So what do we do now that SP3 is out?

**kcnychief** · May 15th, 2008

Have you tested and does it work/not work with SP3? Maybe just need to re-apply the hack if the modified files were replaced with the SP?

**Admiral Michael** · May 15th, 2008

Not yet. Wasn't sure if it would work or mess something up. I only use it on my parents and sister's computer.

**kcnychief** · May 15th, 2008

I haven't used it in a little bit so can't confirm or deny it still functions. It wouldn't surprise me though if it compared MD5 checksums of certain system files and replaced them when the SP was installed. I would think the hack could be re-applied if that were the case, but hard to know

I haven't tested it yet but I found this on Google:

Blocked from work - what does it say?

Here ya go:

If you have multiple users on your Windows XP machine, you might have heard it is possible to patch the terminal services service, to support multiple concurrent remote desktop connection (via RDP) to your computer.

Around the time Windows XP SP1 was released, a patched version of the file termsrv.dll could be found on the Internet, replacing this file with your existing one enabled the concurrent remote sessions support.
Yesterday I upgraded to Windows XP SP3 (you may ask if it isn’t too early? maybe so, but since I’ve already been using the latest RC for some time now, I felt confident enough to apply this update on my home computer). Anyhow, after updating to SP3, I discovered my computer no longer supports concurrent remote sessions.

Short Googling returned few articles explaining how to patch the termsrv.dll to support concurrent sessions, so I pulled out my favorite HEX editor and with few clicks everything was up and running again.

To save so time for other users (and myself when upgrading more computers), I’ve packaged the updated termsrv.dll file with another file that will make the required changes to your registry. (see the included readme.txt file for further instructions).

Download the patched version: termsrv_sp3_patch.rar

Just wanted to confirm that this does work. I tested it on my sister's comp (which is my desktop, I'm loaning it to her as I don't use it. I use my laptop.)
