Winvnc server can be seen via LOCALHOST but not ip/netbios

[hockeyrink]

I'm stumped.

I upgraded from 11b to the latest (RC18), and then I couldn't see my machine from other clients. Sooo, I uninstalled RC18, cleaned the registry, installed 11d (yup, D), but still the same problem.

I keep getting "Failed to connect to server" messages if I use the IP or netbios name of my machine WinXP laptop, but if I use "LOCALHOST", it works fine.

I've repeated this on my desktop Win2k box, with the same results. I can view OTHER servers on the network (except Win2k desktop), but I can't see the laptop locally, or from _any_ other clients on the network.

Using Telnet on my laptop (sb9), using
"telnet sb9 5900" or "telnet 192.168.0.110" comes up with
"Could not open a connection to host on port 5900",

BUT using "telnet localhost 5900" returns
"RFB 003.006" (then a pause, and "Connection to host lost"), which means the software WORKS, but isn't listening to the network.

Some funky stuff is going on here where I can PING and create shares on remote machines, but Winvnc server doesn't seem to be listening to IP or Netbios addresses.

I remembered about "netstat -an", and I ran it on my workstation (192.168.0.11 / sb4). It shows the following:

Hmmm. Ports 5800 and 5900 are only being "listened" on 127.0.0.1 - how do I make it listen on the default IP too?

HKEY_LOCAL_MACHINE\Software\ORL\WinVNC3\

There's some registry settings in here that I found referenced at:http://www.cs.vu.nl/~eliens/documents/vnc/winvnc.html that show "advanced settings".

Didn't realize there were more registry settings, in particular:
LoopbackOnly

Which is apparent what IT does. So I searched for all instances of \ORL\ in the registry, deleted the "WinVNC3" groupings, and reinitialized winvnc.exe.

Back to normal!

Hope this helps somebody else...
