VPN connection terminated (What should I do)

I have a secure Cisco VPN with RSA SecurID token.

Just now When I try and create the tunnel / start the vpn client process, it says :

Secure VPN connection terminated

Reason 412: The remote peer is no longer responding.

The only thing that changed is. The computer to which I remote onto, said it needed some windows updates, so I told the guy at work to let it update then restart the computer.

What should |I do now

Basically that means the connection has been dropped from the remote side... Try running the VPN client as admin and making sure Windows firewall allows outbound traffic on for the vpn client executable.

Dropped from the remote side - so u mean the computer at work ?

Running the VPN as admin - I'm sorry I don't know what that means, could you explain

Windows firewall. U mean the firewall on the computer at work, or in my home ?

(Why would have things changed from yesterday when things were working just fine - is it the updates)

Just to clarrify.

Home computer = remote one (not connected to server)

Work one ( one I am remoting onto - connected to server)

The updates on the work one could have enabled the windows firewall on the machine. Are you sure after the updates that the computer came back on :) Maybe your co-worker did the shutdown and update option.  Or maybe updates are waiting for a reboot and so some services are off when usually they would be on.

hmm, so not a server issue, you're saying defiantly a problem with the computer at my work place that I am remoting on to.

If it is what you say it is, what do i need to do to fix it.

Indeed. As I indicated in my first post, Windows firewall should allow vpnclient.exe to go out. It has a problem with the IPSec traffic that makes up the connection... it's blocking it from going through.
