I have a need to allow multiple users to view the same remote session on a Windows 2008 server. The server is cloud-based and is virtual. I have no physical access to it. I've tried several different combinations (Ultra VNC, Tight VNC, etc..) and tried to run as a service, but also as an application. It appears that installing via RDP somehow screws up how authentication is set up. I've tried various remedies in terms of setting the password after the install, including copying a registry key, also using a freeware tool called vncpwd.exe to no avail. In some variants of this I do get to a ctrl+alt-del login screen, but am thwarted by a cryptic UAC message that never allows me to login.

I'm not wedded to VNC, but I suspect that someone can walk me through setting this up properly.

Am looking for a "free" recipe to doing multiple viewers for same session. I am able to use web-based, but it's not optimal. Running teamviewer on the server is not a "free" option.

"a cryptic UAC message" I'd love to have a look at that :) – Oliver Salzburg Mar 15 '12 at 13:11
Is this a terminal server? There is such thing as an install mode and execution mode on a terminal server. I have never seen it cause issues but maybe registering a service may need it to be in install mode. – Not Kyle stop stalking me Mar 15 '12 at 13:19
Not a terminal server... however, I just discovered via googling that one can do this natively within 2008 server....… Just tried it and it works. – Kendor Mar 15 '12 at 13:21
You should put that in as an answer to your own question (but not JUST the link please ;) ). – Ƭᴇcʜιᴇ007 Mar 15 '12 at 14:13

I recommend using TeamViewer instead of VNC. It's free for non commercial use and it has a presentation mode that does exactly what you are looking for. See my answer to another question to see what Presentation Mode looks like and how it works for inviting others to view it.

Teamviewer is NOT free for server usage. That said, I just discovered that one can do this natively with Windows 2003 and 2008 server.

Took a while to find this, but I can confirm it works:
