UltraVNC

2. It is 5500
3. Unchecked

Thank you for your help.

If anybody has any ideas, either for solving the problem or for diagnosing it, please do post them

I did some googling, and running
cmd and then
netstat -ano

should reveal if anything else was lurking in port 5500, but nothing turned up

I tried the 5500 port from the outside, by running http://www.canyouseeme.org/ with port 5500, and the viewer in listening mode reacts

What else can I check?

When I follow your recipe, I get: Connection failed - Invalid protocol I can still connect normally, i.e. start up UVNC server on either machine,and start the viewer on the other,and then connect. As to the windows firewall, it is always disabled, but just to be safe I also exempted port 5500 tcp on ...

I did try with disabled zonealarm, and antivirus. No effect. To run the normal server and viewer on same machine did not work, because "Loopbacks not allowed", which does make sense. On the Lan, I can run the normal server on my bad machine, and connect the viewer from my secondary machine, no ...

Anybody with a suggestion or hint as to how to diagnose the problem? For I'd prefer not to resort to reinstallation of the entire system.

Installed the Viewer on the secondary (to be supported) machine. Ran SC on it locally, works just fine. Ran SC on my primary machine, connected to the viewer on the secondary just fine. (That machine runs ZoneAlarm and Avast, like my primary) So there must be something on my primary machine that ...

Viewer is 1.0.9.6

I ran the viewer.exe and pressed the delete button.

Unfortunately, still same result.

I can try the reverse route tomorrow, i.e. install the viewer on the other machine (that I don't have right now).

Will be back tomorrow.

Thansk for your help.

ANd with the supplied plugin, I again just get the Server closed connection, the Server running as application.

Thanks for your posting. I tried the localhost address in the file, and now run the winvnc.exe directly from the same folder as the modified helpdesk.txt (on the same machine) but no joy - still Server closed connection. I have no repeater set up, nor any activated plugin (checked when running the ...

I have the latest UVNC and just recompiled SC. I run the viewer in listening mode, and then run SC on another machine. Both run XP SP3. No fancy stuff, no encryption, just the minimum to make a connection. I have ZoneAlarm on both machines, bnut the result is the same whether switched on or off ...
