wat r the software to spy other computer in a lan network? displaying other computer screenplay, can anyone advice? tq

You can try TightVNC

http://www.tightvnc.com/

It's actually a remote desktop utility, but they have this feature where you can be an "Observer" only (you will not be able to control the mouse / keyboard of the remote machine)

But for this to work, you have to ensure the TightVNC client is also installed on the remote computer

any other pay software? acttually i suspect my company got this kind of software in my com. so, how do i check it?

I'm using Ultra VNC to monitor and control the computer in the lab [maintenance]

Some companies (especially software firms) do actually devleop their own in-house monitoring tools. They are pretty difficult to hack/evade/bypass, if you understand what I mean.

The simplest rule - don't do any personal stuff/business/free lance work at your office

-.-. tq sir.

probably through the VNC tunnel

Tight VNC
Real VNC
Ultra VNC
these things can contorl ur pc in LAN or over the internet

also , remote desktop and remote assistance also can
so beware

and yup, some companies develop own softwares or pay ppl 2 develop own remote desktop softwares , very dangerous

If you want to know who is spying you on LAN, maybe you should "tracerout" and see whether the status of certain ports are linked to "certain" computers--IP.

To some extent i guess you can check with antikeylogger softwares to see whether there is any keyloggers installed on ya pc... There are many anti monitoring softwares and tools as well.. but then dont try to evade your company's monitoring tools.. you might end up in more trouble.

Personally, i kinda like radmin, but since its requires a license, happily using ultraVNC now

I'm currently using RealVNC for maintainence over LAN but even on a gigabit network it has a rather terrible lag Anyway to improve the performance?

That's wierd. I'm using TightVNC (same as RealVNC I persume) over WiFi network (11 Mbps) and hardly feel the lag.

Use Fast Compression mode too. If I use Best Compression, the quality is horrible.

Maybe you could disable the desktop background image rendering to speed up the transfer. All my server have the quintesential Windows blue colour back. And I always keep the desktop free from icon clutter
