you havnt set the password up on the client

or you are being blocked by the firewall on the client..

disable windows firewall and see if you can get in

VNC 4.0

by ebrahim.rangwala@chiltern In reply to VNC error

Please check with the firewall.
VNC does not access remote desktop if firewall is on

you need

by david.wallis In reply to VNC error

you need to make sure vnc is loaded on the xp machines and is running. you also have to set a password on the clients too..

we use ultra VNC here and that works fine

Port

by Baxenden In reply to VNC error

Been ages since i used VNC but most other Remote control applications require the correct port setting up within the software so that they both match. I think the default for VNC is 5900

VNC vs Windows Firewall - Success At Last!

by Computer Dave In reply to Port

I've been going nuts over this for a week! I've tried so many solutions and registry hacks that I've lost track.

Here's what I have and what's been happening:
I'm building a new SBS 2003 server and a Server 2003/SQL box. These 2 are on their own switch so as to not interfere with my production SBS server. I have 1 Win XP box on this Pre-Production LAN. I have VNC (free version) fresh from the their site installed on all three: KAS-SBS, KAS-SQL, and KAS-101. All 3 computers are completely patched with everything MS has to offer. Here are the results:
SBS and SQL can see each other with VNC.
SBS and SQL cannot see 101 with VNC.
101 can see both SBS and SQL with VNC.
Using RAS/VPN to connect to SBS, I cannot see 101.

I've been concentrating on SBS because VNC works perfectly in the production environment. I've rebuilt SBS a couple of times but currently I do not even have ISA installed. I've even rebuilt 101 and kept it out of the domain.

The solution for was too simple to see. After reading this article, I disabled Windows Firewall on the XP box and now VNC works in all cases (I haven't tested remote access yet).

VNC uses port 5900 (5800 for a 1-time Java hit) so I suppose i can try opening that port on the XP box. But eventually I will have ISA running on SBS so that will just be an experiment for my own satisfaction.

I hope this helps save someone from banging his head against a door!
