Default Server Password

[Bit7]

OK. I may have just screwed myself but hopefully SOMEONE can help me. I have a machine in a remote location that I cannot physically access for another week. I remoted into a different machine on that same remote network (Win2008R2 Server), used RDP to access my machine (Win7Pro-x64) and installed UVNC Server 1.2.1.2. Of course, upon completion of the install my RDP connection terminated. Now, I can't access that machine via RDP and when I try to use UVNC Viewer to that address I cannot authenticate. Is there a default UVNC Server password I can use to get in to change the Admin Settings? If not, I'll need to wait until next week when I can get there to access it via physical console. Any assistance on this issue would be appreciated. Thanks in advance.

There is no default password...it's a random ascii string created on install.

You cannot install UltraVNC via RDP session. As you have discovered, and I discovered a few months back.
When restarted, the credentials just do not match, and because of that, the uvnc settings are saved on another place in a RDP session, and so they are not correctly reread on restart without the RDP session.

What I do in these cases is:

Open port 5900, so you can reach computer via VNC when it will be installed.
Make a batch script that will be run on computer startup, to automatically and silently install UltraVNC when the OS restarts. (Try it before restarting).
Restart Computer.

On restart, UltraVNC will be installed via the script, with the correct credentials, and will be reachable via port 5900. Connect and configure ultravnc as you like, out of the RDP session.

If you need to automatically logon an user when restart, to execute the script, use control userpasswords2 in a cmd window. Select the user and the password, and it will be automatically logged on when restarted.
