Can VNC automatically reconnect when disconnected?

I have these wallboards that shows incoming and outgoing calls in our call center. It's just an XP sp3 workstation with a large monitor. I have installed RealVnc on these machines and created shortcuts on some clients that needs to see the wallboards but can't physically. But these vnc shortcuts seems to get disconnected once and a while. Is it somehow possible to have vnc automatically re-connect without any user interference?

The .vnc shortcut contains this info:

[Connection]
Host=10.218.110.41
[Options]
UseLocalCursor=1
UseDesktopResize=1
FullScreen=0
FullColour=0
LowColourLevel=1
PreferredEncoding=ZRLE
AutoSelect=1
Shared=1
SendPtrEvents=0
SendKeyEvents=0
SendCutText=0
AcceptCutText=0
DisableWinKeys=0
Emulate3=0
PointerEventInterval=0
Monitor=
MenuKey=F8
AutoReconnect=1
PassWord=

If this is not possible, does anyone have an alternative to vnc that could do the trick.

AutoReconnect=true/false

    When an error occurs that causes the VNC connection to be closed, VNC Viewer can offer to reconnect to the server, using the same username and password. This option applies only to connections made from viewer to server, and not to reverse connections.

As inferred by David_Hagerman above, there doesn't appear to be any facility to have VNC automatically re-connected, without a User intervening.

You can see a reference to this situation if you scroll to sub-heading "Offer to automatically reconnect" in this next article:

I have seen that article, but it seems to be no good.

Do you know of any other solution I could use to mirror the desktop of a pc to a number of pc's?

We use this facility and if the vnc connection hangs then it prompts the user to reconnect.unfortunately if the machine is disconnected from the network vnc sees it as a the user disconnected the session and doesn't prompt. Are you suing security on the connection for the user? is there something stopping the users from connecting to the machine again?

There is no problem with reconnecting manually - the user just double clicks the vnc shortcut I created. But I want to use this vnc shortcut on an unattended pc, and there I get the problem when it disconnects

right I get you now. You can use Team Viewer for this scenario

you can just allow Lan connections and if you then go to the connection tab you can set up unattended access.

please let me know if this works better for you

I will try this tomorrow, but doubt it will do the trick.

Basically I have 1 master monitor and 5 slave monitors - all on the same network.

I need the slave monitors to show what ever the master is showing, and I need it to be unattended. If the master gets rebooted, the slaves should automatically reconnect. The same if a slave is rebooted it should automatically start showing the master desktop. I know it is possible with some sort of vga splitter, but I would prefer a software/network based solution
