Authentication rejected

Post by ASF »

I have installed UltraVNC on two PC's that I am currently logged into via RDP. I have set a 6-character password, but whenever I attempt to connect from either of the PC's to the other using that password, I get "authentication rejected". I installed using all default settings and am at a loss as to what I could be doing wrong. Can anyone assist?

The password is in the ultravnc.ini, if for some reason the user don't have permission to save at this location it fail.

At your home pc, copy winvnc.exe to a temp folder, run winvnc from there and set a password.
Now you have a ultravnc.ini in the temp folder.
This is portable, you can copy it to the eral folder of winvnc.exe (C:\Program Files\uvnc bvba\UltraVNC)
