unable to connect to host: Connection refused (10061)

[Craig Smith]

I have looked through many messages dealing with this issue and have 
tried many of the suggestions without any resolution to the similiar 
problem I am having.  I am using 4.1.2 on all the machines in our 
offices.  Our 4 sites are behind Symantec VPN routers.  Within our 
domain I am able to VNC to any machine except for 2 which are giving me 
the grief.  They are both laptops, one a Sony Vaio and the other an IBM 
T43 ThinkPad.  I can VNC in to any other machine from the outside as 
well, when opening a port on the router.  The 2 laptops do not allow 
this either.  The domain has a group policy which disables the XP 
firewall.  I have removed the Norton Internet Security 2006 from the 
Vaio and don't believe that eTrust is causing the issue on the 
ThinkPad.  I have looked through and compared many of the services to 
the desktops which don't have any issues with VNC and have found nothing 
that solves my problem.  The only other behaviour I find interesting is 
that if I connect from the laptops to any other machine first, then the 
laptops will allow a VNC connection from the other machine following 
this, until the next reboot.  As there are also switches between the 
router and the laptops I wondered if this might be causing the problem, 
but it does it with a direct hookup to the router as well.  Also, from 
within I get the error "unable to connect to host: Connection timed out 
(10060)" while from outside I get "unable to connect to host: Connection 
refused (10061)".  Any ideas or suggestions would be greatly appreciated.
