UPDATE: Note that I have given up on UltraVNC and gone to RealVNC because it supports 4 monitors (and I find TightVNC just too slow when the screens are busy). Pay the $30 for the Personal version and save the time.
Sooo, I needed a fast VNC that would support multiple monitors so I can run some digital signage and digital artwork remotely on Win 7 64 Bit. Previously I had used the standard REALVNC but it has problems with running as a service in 64bit PC’s, which I had previously tollerated on my Windows Vista implementations. It’s been a few years and so I took another crack at it and found that the current build of UltraVNC:
- supports multiple monitors
- supports Windows 7 and Server 2008 R2
- supports 64 bit
- supports Active Directory tie in
What it can’t seem to do is consistantly get past the Windows Login/Logon screen. From several blogs, the cause is apparently that UAC has to be ENABLED, which in my case is not a problem, because I always leave UAC on under Windows 7. CTRL ALT DEL usually has no apparent response from the host PC. After playing with settings and reading blogs I found three suggested work arounds, two of which was a good one:
- Disable the CONTROL ALT DEL (C A D) requirement via the registry (this is a VERY bad idea in corporate environments that should get you fired).
- Click the blue wheel (Ease of Access) icon in the bottom left corner of the screen and select TYPE WITHOUT THE KEYBOARD – ON SCREEN KEYBOARD. The problem with this option was that the screen would not refresh automatically… which is annoying. See REFRESH SOLUTION below.
- I also found that putting the ultraVNC client into FULL SCREEN sometimes let me use the SEND CONTROL+ALT+DEL key
NO SCREEN REFRESH:
From http://www.appdeploy.com/messageboards/tm.asp?m=76509 I found the solution was to change the following settings in C:\PROGRAM FILES\ULTRAVNC\UltraVNC.INI
