When the connection window pops up

Enter the appropriate username and password (also ask your network administrator).

For later convenience, check the following user to save the user name and password, select any person who uses this computer.

Then click Connect and the VPN connection is successful.

If not unexpectedly, you will be prompted "error 800: Unable to establish a VPN connection"

Because the windows2000/xp/2003 system has IPSec enabled by default, IPSec features should be blocked when initiating a VPN request, and the registry needs to be changed for Windows Registry Editor Version 5.00[hkey_ Local_machinesystemcurrentcontrolsetservicesrasman Parameters] "prohibitipsec" =dword:00000001 can be successfully connected by restarting the operating system after modification.

Modifying the registry looks like a very advanced thing, I tell you a simple way.

Copy the contents of the above to Notepad and save as a Vpn.reg file

Then double-click the Vpn.reg file to select it.

Modify the registry, computer restart double-click the desktop to "my company" as the name of the icon, click Connect. Of course, after use, remember to disconnect, but also double-click the desktop to "my company" as the name of the icon, click Disconnect. But sometimes there will be some other problems, please refer to the following methods to solve. When connecting to a VPN, the prompt 800 error resolution is the most immediate way to remove the original VPN connection and rebuild one. If you still do not see the following careful analysis and processing of VPN connection occurred "error: Unable to establish a VPN connection" is generally the following reasons:

1. Check the configuration "host name or IP address of destination" uses domain name instead of IP address, because the VPN needs to be maintained regularly, we may change the VPN server's IP address, but the domain name will not change.

2. Your network and our VPN server does not have the correct channel, please try to replace the "destination host name or IP address" in the configuration, adjust it to our login server IP address or domain name.

3. Temporary failure, most likely because you are using a DNS server busy unable to resolve the server IP address or domain name, you can use the following actions: Start-> Run-> open:cmd-> OK, execute command ipconfig/flushdns And then make a VPN connection attempt. (This comparison often occurs, commonly used)

4. Because of the inability to connect due to configuration exceptions, although the user has not made any configuration changes, due to internal failures in the system will cause configuration (registry information) exception, which is a common problem in Windows system. The processing method is to remove the configuration of the original VPN connection and re-establish a new VPN connection. Common

5. Check that the security parameter configuration of the connection is consistent with the configuration requirements.

6. The firewall rules on your machine are too restrictive to connect externally, please adjust or close all firewalls and try again.

7. If you have a user who has a home gateway installed, it is also recommended that you restart your home gateway device.
