kde has desktop sharing built in it's in the system menu and there is tightVNC for the windoze side
the big bug I have found with tightVNC is that it dose not work with local host (127.0.0.1) but needs the real ip instead that bug may be fixed now

ultraVNC may be what your looking for

when running on an ad hock network side by side it dose get confusing because it's easy to lose track of just witch computer what is running on

The only things about VNC are it's third party and needs to be installed on Windows, and it has no default encryption, so you would want to use it only on a LAN or via VPN, even though I also recommend using RDP over VPN, RDP can use SSL for the connection.

I don't know if the problem still exists, but after spending a lot of time regarding this topic a colleague of mine came up with iTap. I give it a try when I am home and keep you informed.

Cool, thx.

...just note for people: it'a 14-day trialware. So it's not a free solution.

Indeed it worked surprisingly well.

I put in the necessary data, server name, name of computer, login id and password (I had already installed the certificate from my company) and started the connection. And I was on!
Connection is a bit slow with GUI-heavy applications (at least with my bandwith and latency) but feasible. I noticed some mouse cursor dropouts with lotus notes, but everything else worked just fine.
The Demo has a 10 minute limit, but you can get a 14 days trial period. After that it's 20€. I'd prefer it free & open, but at the moment there's nothing else available.

Regards
