If windows firewall enabled on XP SP2
vncviewer ...Lookup server address ... Failed to get server address !
vncviewer can't reach vnc server by hostname address
remote desktop connection (mstsc.exe) can't reach remote desktop by hostname
netbios name filtered, hostname blocked by windows firewall XP SP2
use ip address instead of the hostname address
disable windows firewall on XP SP2 if you have already an NAT/firewall on your broadband router,
so you can reach again yours vnc servers by hostname on your local area network (LAN)
manually add DNS IP address to your broadband router
exclude the vnc server/vnc viewer computer outside of DHCP range or reserve MAC address/hostname to DHCP range
How to Debug "Failed to Connect to Server" Version 2 (Updated 2007-4-6)
How Do I Install UVNC As A Service
WinVNC must be installed and run as a service to be able to do this operation.
You can use the corresponding UltraVNC Server menu shortcut to install this service (from the Start Menu).
You can also do this using Command prompt:
C:\program Files\UltraVNC\WinVNC.exe -install
- reboot the computer
- Execute: net start winvnc, in the command prompt.
WinVNC is installed and run as a service
then I double clicked the (Tightvnc viewer-Listen Mode), entered the IP adress and the password as usual ... and it worked.
install any VNC flavor by remote desktop Terminal Service
and prevent VNC default password not set
UltraVNC as a service via RDP will not prompt to set default password no matter what options are chosen. UltraVNC as a service must be installed locally for it to work properly.
2. I installed ultravnc. At this point I was having all the problems as everybody else
3. With registry editor, I browsed to HKEY_LOCAL_HACHINE\SOFTWARE and then created some the"ORL\WinVNC3\Default" keys (which are case-sensitive and without quotes):
a) created a key named ORL
b) under ORL I created another key called WinVNC3
c) under WinVNC3 I created on last key called Default
4. I then proceeded to install VNC as a service through the start menu, and nothing else (don't fiddle with any more ultraVNC icons for the moment).
5. Download the vncpwd application which you can find at http://www.sysworksoft.net/products/vncpwd.html and unpack it somewhere you can use (or you might just keep it somewhere like c:\windows\system32
6. run vncpwd from the command prompt as follows:
7. Restart the computer. This is very, VERY important. Restarding the service didn't worked for me and I was still getting the "no password" error. Only after I restarted the server that things worked out.
I have no problems installing Ultravnc as service (and mirror driver) from remote desktop/TS - if I first populate HKEY_LOCAL_MACHINE/Software/ORL/WinVNC3 with the Password entry copied from another installation.
I have first installed Ultravnc as service on my local PC and configured default password. Then I export HKEY_LOCAL_MACHINE/Software/ORL/WinVNC3 from regedit to a flat file. This file can be copied to the RDP/TS server and imported with regedit. Once this is done, UltraVNC can be installed normally as service, and it will be ready to connect to with VNCviewer and the same default password as the original local PC. Then you can change password/auth.
Now since VNC is hooking video as if we were sitting in front of a console rather than RDP's session stuff, we can attach to the newly started vnc service. Go to start->program files->Ultra VNC->Ultra VNC Server [folder]->Show Default Settings (Assuming everything is in the default places/names at least...)
Now set your password. Do a save and get outta there. Exit VNC client locally, and reconnect - now it prompts for password. Remove the authrequired key.
