This server does not have a valid password enabled ...

[nigelmercier]

I'm getting the error "This server does not have a valid password enabled ..." even when using loopback.

Server installed on Windows Home Server 2011 via RDC.

That seems to end up here http://forum.ultravnc.info/viewtopic.php?f=3&t=31276

I found a program in the install folder called passwords, it flashes up a cmd window. After running it I now get a different error.

Further to last, which I can't see yet. I've done the procedure in my link, same problem.

[Rudi De Vos]

syntax
setpasswd.exe myfullpasswd myviewonlypasswd

just make sure you run setpasswd.exe with runas admin else you don't have permission to change the ultravnc.ini file

open a cmd with runas admin
goto program files ...
run setpasswd.exe myfullpasswd myviewonlypasswd
(if you run setpasswd.exe without a parameter, it set a random password)


Keep in mind that even when you logged on as administartor you are still a normal user.
Only when you start an exe with "runas administrator" ( right click) you are the pre Vista admin.

It's simpler to start uvnc_settings.exe with runas admin and set the password via this tool.

I've now tried all the above, same problem.

Is uvnc running as service ?

Check file content of ultravnc.ini

[ultravnc]
passwd=jhfzekfzaekfâ <<<<

do you see a line like this

[nigelmercier]

I've uninstalled the service for the moment.

Yes, the ini file has a password entry.

[Rudi De Vos]

If you run winvnc.exe in the same folder as the ultravnc.ini with password, does the app still tell it has no password ?

Service:
Using the service manager, verify if the service is reffering to the same folder.

In the past we had some nasty issue's with vnc installed at 2 different spots.
service was using folder A while we did all changes on folder B.

To avoid all security issue's.
create a new folder on the desktop and copy the content of the install folder to desktop/uvnc.
Now we know that the current user has full permission.
You can test this by opening ultravnc.ini with notepad and try to save it at the same spot.

Start winvnc from desktop/uvnc spot and set the password via the normal systray icon or properties popup.

When this works, copy all back to the installed forlder.

C:\Users\Administrator\Desktop\UltraVnc\winvnc with LoopbackOnly checked
C:\Users\Administrator\Desktop\UltraVnc\vncviewer with VNC Server: localhost
I get "Your connection has been rejected"

[Rudi De Vos]

Your connection has been rejected

You can only get this warning in 2 cases.

1)to many wrong passwords , ip was blacklisted
-restart winvnc to unblock
2)you have set something in
AuthHosts= ( ultravnc.ini)
ip adresses with a - are rejected

erase ultravnc.ini
and restart winvnc.exe
in the properties that popup
set passwd and check allowloopback or loopbackonly

[nigelmercier]

Your connection has been rejected

...
erase ultravnc.ini
and restart winvnc.exe
in the properties that popup
set passwd and check allowloopback or loopbackonly

Did this, back to "This server does not have a valid password enabled ..."

I even tried the set password utility, same.

[Rudi De Vos]

please copy the ultravnc.ini content.

This file is correct and you proper can connect with a viewer in loopback. (tested)
Using this ultravnc.ini winvc works....on my pc.

winvnc.exe use the ultravnc.ini file in his folder.
The only thing i can think off is that the service is back online and using the ini file from "program files"

net stop uvnc_service
replace ultravnc.ini (program files) with the one from C:\Users\Administrator\Desktop\UltraVnc
net start uvnc_service

[nigelmercier]

replace ultravnc.ini (program files) with the one from C:\Users\Administrator\Desktop\UltraVnc

I moved the folder from Program Files, not copy.

[nigelmercier]

Cracked it!

There were no VNC services running, and no remnants left in Program Files. However, I did a search and found the UltraVNC.ini file that I had copied direct onto the Desktop (no folder). It seems the UVNC was picking this up in preference to the one in Desktop\UltraVNC

Thanks for all your help.

RATS!

Spoke too soon. I should probably start another topic, but I'm now attempting to connect via another PC on the same LAN.
I've unchecked LoopbackOnly, and put the IP address of the server into the Viewer. Is there anything else?

I get Failed to connect to sever !
