Secure VPN connection terminated locally by the client. Reason 414: Failed to establish a TCP connection.

At the end of last week I updated my Windows XP with SP3. After a while I’ve tried to connect to the company network using Cisco VPN client and it failed to connect with the error stated in post’s header. If you look in the log you can see that the client tries to connect the server but for some reason it is impossible.

After analyzing what was installed and what was changed it was clear that the SP3 update causes the error. I’ve checked the version of my VPN client which was 4.0.3. According to the information in the internet this version of Cisco VPN client has problems with SP2. Well, I had SP2 and it worked fine but with SP3 it doesn’t. In Microsoft support has an article that says about problems with SP2. I replaced Cisco VPN client 4.0.3 with version 5.0.0 and it works fine now.
