This isn\'t intended to be an introduction to VNC - have a look at the Getting Started page first.
This list is being updated regularly, so, particularly if you are reading a local or mirrored copy, it\'s worth checking the original from time to time. The archives of the mailing list are also available, and they can be a good source of help - try searching them here.

VNC Frequently Asked Questions
Getting Started
Q1 Where can I get VNC?
The latest versions of VNC and this documentation are always available from the AT&T Labs Cambridge web site at
http://www.uk.research.att.com/vnc. In addition, various add-ons, extras, and ports to other platforms can be found on the contribs page.
Q2 I thought this was something to do with ORL? What\'s the Olivetti/Oracle link here?
In January 1999, AT&T acquired ORL, the Olivetti Research Laboratory founded 12 years earlier, and recently jointly funded by Oracle, to create AT&T Laboratories Cambridge.
Q3 I downloaded the .EXE files and they don\'t work!
Netscape used to have a nasty habit of sticking a .EXE extension on a file when it thinks it knows what type it is. When you fill in the download form you specify the type of compression you would like to use, and this does not include .EXE, so if the thing you downloaded has that extension, change it to whatever you requested (usually .tgz) and then unpack the files using an appropriate decoder.
Q4 I ran SETUP.EXE but it didn\'t work/nothing happens.
Setup often doesn\'t work if you\'re running it from a network drive. Try copying it to a local drive first. If you\'re on NT, make sure you have NT service pack 3 or later installed. It appears that the InstallShield system we use won\'t work without it.
Q5 I ran WinVNC, but nothing seemed to happen. I don\'t see an icon on my taskbar.
If you are using a version earlier than 3.3.3, we suggest you upgrade. If you are using 3.3.3 or later, this is because WinVNC doesn\'t know that somebody is logged in. On Win95, this will happen if you bypass the \'password\' prompt at login. If you do this often, you might want to consider setting an empty Windows password, so you don\'t get prompted!
If you\'re running WinVNC as a service, it may be that the service has not been contacted by the \'Service Helper\' when you logged in, to tell it who you are. (See the WinVNC docs for more details.) You can try running the Service Helper from the Start Menu to see if this is the problem.
Q6 WinVNC causes a \'Blue Screen of Death\' on NT!
Again, make sure you have Service Pack 3 or later. If this happens it is usually due to bugs in Service Pack 1. Also note the Service Packs\' warning that if you add or change components on your system you should reapply the service pack. If this doesn\'t fix it, check for updates to your network and graphics drivers. VNC makes very extensive use of both your video system and your network, and has a tendency to find any bugs in either of them! There may well be bugs in WinVNC, but we know of people running it on thousands of machines without problems, so please check other parts of your system before assuming it\'s directly a WinVNC problem.
Q7 I get an error message about \'disabling Nagle\'s algorithm\'. What does it mean?
Nagle\'s algorithm is an optimisation which is used most of the time on socket connections. Under certain circumstances it batches up lots of small transmissions into bigger ones, to make better use of the bandwidth. VNC relies on small transmissions (like mouse movements) getting through quickly, so we turn it off using the TCP_NODELAY option. If this causes an error, it is a problem with your TCP/IP stack. In particular, Microsoft have broken this with NT service pack 6, but we hear that the hotfix mentioned in KB article Q245678 will fix it. If this doesn\'t work, you could try the security patch mentioned at
http://www.microsoft.com/technet/security/bulletin/ms99-046.asp. We\'ve heard that this fixes it as well, though this may just be a fix for an incomplete SP6a. In a future version of VNC we will pop this up as a warning without making it fatal.
Q8 I get an error message about \'Planar vs Chunky\' screen formats. What does this mean?
This error usually occurs when running WinVNC on a Windows 95/98/ME or Windows 2000 machine with a 16 colour (NOTE: NOT 16-bit) display mode. The problem is due to the way the 16-colour VGA display driver represents the screen internally. Upgrading the display drivers to hardware-specific ones or increasing the number of colours (to 256 colours, 16-bit or 32-bit, for example) should fix the problem. Windows NT does not exhibit this problem.
Q9 How do I set up a Windows 95/98 machine so that I can dial into it directly and view it using VNC?
You need to install your modem from the control panel if you haven\'t already, and you need to set up the dialup networking server on your server machine. (This is included with Win98 and NT4. On Win95 it is in the Plus! pack, but you need to get an update to version 1.3 or later from Microsoft\'s site. At the time of writing it can be found here.) You can enable the dialup server from the \'Connections\' menu of the dial-up networking window. If it isn\'t there, or if you\'ve updated the dialup networking as mentioned above, you need to install it using the Windows Setup section of \'Add/Remove Programs\' in the control panel. When it\'s running and you\'ve dialled in, the server machine should have an IP address something like 192.168.55.1 as seen from the viewer - you can find this out by hovering over the VNC server icon, using \'netstat -r\', or running winipcfg. You should then be able to connect to, for example, 192.168.55.1:0.
