Hi,

I have a laptop that wont connect using VPN it used to work fine and then when It was connected to another network for the day it stopped working. It is able to connect to the internet and networks ect and It is not using Dial up or a Modem. I have tried to connect a few times now and It still gives the same error. However other laptops can connect to the same VPN. I have also tried connecting with the firewall disabled so it is not a firewall fault. The Laptop is running Win 7 X64.

What exactly is the error?
Is the IP space of the new network the same as the IP space on the VON network?

Sorry thought I had put it in the message the error is

A connection to the remote computer could not be established, so the port used for this connection was closed. (Error 619) For customized troubleshooting information for this connection, click Help.

port closed means port closed. Is there another firewall in this new network?

We have got a Hardware firewall and each machine has microsoft firewall installed. I have used a port checked and the port is open but when I try and telnet onto the port I get an error saying "Could not open connection to the host, on port [1723]

So you can connect to your VPN from another network on port 1723.
From this one particular network you cannot connect.
Can you see the firewall logs on your machine and that hardware firewall?

I can connect through the VPN from other laptops but not this one. It started happening after it was taken off site and connected to a customers network.

I have had a look in the event viewer and have found these errors:

Error 1

A connection to the remote computer could not be established, so the port used for this connection was closed. (Error 619) For customized troubleshooting information for this connection, click Help.

Error 2

The name "CONTIGO        :1d" could not be registered on the interface with IP address 192.168.123.77. The computer with the IP address 192.168.123.201 did not allow the name to be claimed by this computer.

Error 3

The browser was unable to promote itself to master browser.  The computer that currently believes it is the master browser is unknown.

Error 4

The DNS proxy agent was unable to allocate 0 bytes of memory. This may indicate that the system is low on virtual memory, or that the memory manager has encountered an internal error.

Error 5

The DHCP allocator has disabled itself on IP address 192.168.123.77, since the IP address is outside the 192.168.137.0/255.255.255.0 scope from which addresses are being allocated to DHCP clients. To enable the DHCP allocator on this IP address, change the scope to include the IP address, or change the IP address to fall within the scope.

Error 6

CoId={BDB10C13-6DFF-4489-B2EE-447DDFB13504}:The initial Secure Socket Tunneling Protocol request could not be successfully sent to the server. This can be due to network connectivity issues or certificate (trust) issues. The detailed error message is provided below. Correct the problem and try again.

Just to note that the Laptop is using DHCP and it's Current IP is 192.168.123.77 I have released and renewed the IP to see if that caused the issue but the problem is still there also there are a few more errors below:

Error 1
The requested name is valid, but no data of the requested type was found.

Error 2
CoId={986E80E3-D739-4473-969F-E5ABEA346044}:The initial Secure Socket Tunneling Protocol request could not be successfully sent to the server. This can be due to network connectivity issues or certificate (trust) issues. The detailed error message is provided below. Correct the problem and try again.

Error 3
A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file.

Error 4
The client was unable to validate the following as active DNS server(s) that can service this client. The server(s) may be temporarily unavailable, or may be incorrectly configured. 192.168.1.1

I'd think it's not a VPN question but a networking one.
Check the time zone? and time?
Does ipconfig/all return the correct data?
Does your DNS or DHCP server have an old entry for this machine (reverse or forward) with another IP address?
Has another machine got an address that this machien might use?

The IpConfig returns the correct data and the timezone is correct. Also the DNS or DHCP should not have any old entries for the machine but I will check. I have renewed the Ip address a few times now and it is still not working so I am sure that there is not any other machiens with the same IP address.

I couldnt figure out how to solve this so I had to re-image the machine. All the settings were correct including DHCP and timezones ect and still no joy I couldnt afford to spend any more time without VPN so I had to re image the laptop. This solved the issue.
