I am new at using UltraVNC.  I like what I see and it will definately solve some of what ails me.  My issue is I get a VNC Authentication failed message between some computers.  I can go to another computer and connect to the same computer and I get in.

Does anyone have any ideas?

CPU A:  has UltraVNC server installed and running
CPU B: cannot connect to CPU A and gets a VNC Authentication failed message
CPU C: can connect to CPU A using the same password.

CPU B  can ping CPU A.

CPU A:  Has VNC server registered as a service
CPU B:  Has VNC server registered as a service
CPU C:  Has VNC server registered as a service

CPU A can view and control CPU B and C.
CPU C can view and control CPU A and B.
CPU B can view and control CPU C.
CPU B can 'see' CPU A.  CPU A issues the screen asking for the password.  User on CPU B enters the password.  CPU A issues a 'VNC Authentication failed' message.

I uninstalled UltraVNC from CPU B.  I reinstalled on CPU B.  Now CPU B is working correctly to all computers.

Thanks for your help!
