I've installed RealVNC server (Windows), authentication mode was set to VNC password (there is no user name to fill).
When I tried to connect to server via the viewer, it asks for password and USERNAME.
But there is no username configured on the server! I think I've enabled "Admin" check box in one of the options tabs. Could this be a reason?
What to do?
It might be easier to set the account to login automatically, but with a password enabled.
This link shows XP, but I'm 90%+ sure that the syntax is the same for 7: http://wiki.ljackson.us/Control_Userpasswords2
These are two other ways to get the the control panel item:
WinKey+R > control userpasswords2
Start > Search > netplwiz
When in service mode, you should have a task-bar icon:
Right click over the task-bar icon;
Select "Options...";
If UAC is active, select yes;
From the window presented, access the first tab "Connections";
Click on Configure...;
Set your VNC Server password, repeat the password and press ok;
You're set, you should now be able to connect to your VNC Server with the password you've just set.
If you don't see the tray icon, you can activate it using the windows Registry editor:
Click "Start";
On the search box, type "regedit" and press enter;
On the left column, navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\RealVNC\vncserver
On the right, you should now see a REG_DWORD Value named "DisableTrayIcon";
Right click over it and select "Modify...";
The value should be set to "1", replace it with "0" to show the tray icon;
Press OK, as soon as you press it, the tray icon should appear.
Best Answer
If you have set the server to VNC authentication and are being prompted for a username the chances are you have configured the extended VNC authentication for the Admin or ViewOnly account.
You can either leave the username blank and just enter your vnc password, or if you don't want the extended authentication, from the Server's options dialog, select the "Configure..." button next to VNC authentication and disable the Admin or ViewOnly account.
You may have also turned on guest access, that also prompts you for a username.
