HELP: Connection failed - Invalid protocol !

SneakerPimps · Post by **SneakerPimps** » 2005-09-01 20:32

Hi,

Just wondering if someone can help me, I just can't figure out how to fix this problem!!!

Version: UltraVNC 1.0.1 (Latest)
O/S: Win2K SP4

Okay, I previously used RC18, which worked fine until one day it gave me a similar error to the above (picture). So I downloaded the latest version and tried install that. Same error popped up.

I uninstalled the RC18, and deleted the remaining folder in program files then installed 1.0.1.

I have tried uninstalling 1.0.1 and reinstall many MANY times.

I have tried cleaning the registry then reinstalling.

It's driving me insane, because I just can't get it to work. I have installed 1.0.1 on other machines at the same location and it worked flawlessly.

I don't use DSMPlugin, never have in the past, but I have tried just for the sake of it. It still give me a similar error, but with a "please check your DSMPlugin config...".
Can someone please help!

Much appreciated,
S.P.

Yeah, I've done that.

It's a Win2K box, with no firewall, except NAV2005, but I have added the exception in.

Funny thing is that I have another 4 box which are identical, and they worked without any trouble.

All computers are static.

1 bad quality network cable or wrong network card config ?

Well, for the meantime I reverted back to normal winvnc, and it works absolutely fine.

I'm really stumped

It's to a point where I feel I need to format the machine just to get UltraVNC working.

Rightclick on the eye icon (VNC) in systray. Select Admin properties and disable DSM plugin.

That should work.

I finally managed to fix it. Well I don't think it is properly fixed until I format or something.

Basically I enabled the DSMPlugin and generated a key then applied to the Server config. Then did the same for the viewer. It works, but it only worked if I don't use MSLogin1 or 2 on the Server config. I just use plain password, the second I try MSLogins it give me that stupid error.

Oh well, at least it works.
