VPN and VNC Again

I get a connection timeout error when I type in the IP address in the VNC viewer. I never get the password prompt. The work PC is Windows 2000 Professional and the home PC is XP. What firewall are you talking about? I have a VPN connection which gets me through the firewall I thought. Once I am the VPN connection in I can use Remote Desktop application to get from my home XP to 2 Windows 2000 servers (one in the internal network and one in the network DMZ). So it would seem that I could also use the VNC viewer. I have Zone alarm, I think, at home. I had turned it off at one point and tried the connection but still got the connection timeout.
One weird thing is I can type in the machine name in the VNC Viewer (minus the true domain) and get a different error message. For instance, name.domain.gov gets an error about being in a database but not being able to resolve or something (I can copy out the error next time I log on if that will help) but if I type in the workstation's true domain name, Ex name.subdomain.domain.gov I get the connection timeout.
What I can't understand is if it is a VPN issue, why would I be able to ping the workstation just fine? How can I test if somehow that port 5900 is blocked even when I am in the VPN?
(Yes, that was a mistake, sorry James! I thought I had resent it to the list after I realized what I did)

There seem to be a lot of problems with VPN. A bit more info would really
help us diagnose your problem and get you up and running. First, what do you
mean by "I can't get it working"? Do you get a password prompt, followed by
an all-black screen and then a disconnect? If so, that's a fairly common
problem, and will require a bit of technical "know-how" to fix. Do you just
not even get a password prompt? What operating systems are we talking about
here? Is your workstation at the office Windows XP, and do you have the
Please get back to us with more details. Just remember, that this is
primarily a user-to-user support, even though James Weatherall from RealVNC
hangs out in this group...

Forgive if the answer to this question is in past lists. I have been
searching and can't seem to find it.
I am using Cisco's VPN Client 4.0.1 to access the lan at work. I
can remote desktop into the servers that I need to get to once I have the
VPN connection. My problem is I installed RealVNC server on my work pc
(Windows 2000) to try to access it from home using the VNCViewer and I can't
get it working.
While I am tunneled in to the LAN I can ping my work pc, but I get a
connection timed out if I enter that same IP into the Viewer. At work, to
test I tried to connect to my work pc from my work pc (the VNC server). I
can connect using both the Java Viewer and the VNC Viewer so I assume the
VNC server is configured correctly.
From home thru the VPN to connect to any shared drives I always have
to log in with my network password. I am wondering if this has something to
do with it. Reading the lists, someone had mentioned after you make a
connection this way or in Outlook you should be able to use the VNC Viewer
but I still can't.
Any advice for a non-techy?
