1) you are dialing the wrong number.
2) make sure you have good connection.
3) If using VPN, make sure the port 1723 and IP Protocol 47 (GRE) are opened.

Receiving the following error while trying to connect to VPN using F5 network VPN adapter.Error 721 - the remote computer did not respond


use the router's public IP address for PPTP requests, instead of one of the other public IP
addresses our ISP assigned us, and simply forward PPTP (TCP 1723 & IP 47)
requests to the internal servers. Therefore, the only difference is that I
am using a pingable IP address which happens to belong to the router instead
of using one of the public IP addresses I have NATed. For whatever reason,
this solved our problem with connecting to the RAS server. We no longer have
to retry up to 6 times to successfully connect

Second , See if port 47 is blocked....

Let me know if this works

VPN in Microsoft Server 2003


The full form of VPN is Virtual Private Network. VPN gives extremely secure connections between private networks linked through the Internet. It allows remote computers to act as though they were on the same secure, local network. Allows you to be at home and access your company's computers in the same way as if you were sitting at work.

Almost impossible for someone to tap or interfere with data in the VPN tunnel. If you have VPN client software on a laptop, you can connect to your company from anywhere in the world. VPN goes between a computer and a network (client-to-server), or a LAN and a network using two routers (server-to-server). Each end of the connection is a VPN "endpoint", the connection between them is a "VPN tunnel".

When one end is a client, it means that computer is running VPN client software. You can use a virtual private network (VPN) to connect components to one network by using another network. VPN do this by "tunneling" through the Internet or another public network. With a VPN, connections across the public network can transfer data by using the routing infrastructure of the Internet, but to the user, the data seems to travel over a dedicated private link.

A VPN gives you the benefit of a dial-up connection to a dial-up server, plus the flexibility of an Internet connection. Using an Internet connection you can connect to resources all over the world. If you have a high-speed Internet connection at your computer and at your office, you can communicate with your office at full Internet speed. This is much faster than any dial-up connection that uses an analog modem.

VPNs use authenticated links to make sure that only authorized users can connect to your network, and they use encryption to make sure that others cannot intercept and cannot use data over the Internet. A Tunneling Protocol is a technology that helps make the transfer of information over the Internet more secure from one computer to another.

VPN technology also permits a corporation to connect to its branch offices or to other companies over a public network, such as the Internet, while helping to maintain secure communications. The VPN connection across the Internet logically operates as a dedicated wide area network (WAN) link.

VPN in Windows 2003 Server: You need a high speed Internet connection to configure and run VPN server. Two individual lan card must be present in a single system where you want to configure a VPN Server. The lan cards should ping each other. Also need a User which's Dial in allow access should be enable. Microsoft 2003 server two tunnelling protocols for a secure VPN connection, one is PPTP (Point-to-Point Tunnelling Protocol) which Provides data encryption using Microsoft Point-to-Point Encryption. The other is L2TP (Layer Two Tunnelling Protocol) which Provides data encryption, authentication, and integrity using IPSec.

Steps to create VPN Server in 2003 Server: At first I go to Start and point to Administrative Tools, then click Routing and Remote Access. Then I click the server icon that matches the local server name in the left panel of the console. If the Routing and Remote Access service was previously turn on, you may want to reconfigure the server.

To reconfigure the server Right-click the server object, and then click Disable Routing and Remote Access. Click yes to continue when you are prompted with an informational message. Then Right-click the server icon and then click configure and Enable Routing and Remote Access to start the Routing and Remote Access Server Setup Wizard. After that click Remote access (dial-up or VPN) to turn on remote computers to dial in or connect to this network through the Internet. Then I have Click to select VPN. In the VPN Connection window I click the network interface (Lan) which is connected to the Internet and go the IP Address Assignment window, then I click Automatically because there was present a DHCP server in network. However, if DHCP is not available, you must specify a range of static addresses.

If you use from a specified range of addresses, open the Address Range Assignment dialog box and Type the first IP address in the range of addresses that you want to use in the Start IP address box. Type the last IP address in the range in the End IP address box. Windows calculates the number of addresses automatically. After that I have accept the default setting of No, use Routing and Remote Access to authenticate connection request and finally Click Finish to turn on the Routing and Remote Access service and to configure the server as a Remote Access server.
For the remote access server to forward traffic properly inside your network, you must configure it as a router with either static routes or routing protocols, so that all of the locations in the intranet are reachable from the remote access server. It also need for security purpose.<SPAN style="LINE-HEIGHT: 115%; FONT-FAMILY: 'Verdana','sans-serif

I am having problems connecting VPN Connection on my Windows 7, it says there need to be a machine certificate installed before i can connect using L2TP/IPsec. error code :766


"Error 766: A certificate could not be found. Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate."

"Error 766: The L2TP connection attempt failed because the security layer could not authenticate the remote computer."

Cause: Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate. You will see this error message when such a certificate is not available.

Typically, this error is generated on a remote access server that has active L2TP ports configured, the remote access service started but there is no certificate in the computer certificate store. This generates an event log message that tells the administrator that L2TP ports will not be able to accept calls until a certificate is acquired and RRAS is restarted.
Resolutions: 1. If you use PPTP VPN, select Automatic in Type of VPN.
2. If you use L2TP, check the remote access server and make sure there is certificate in the computer certificate store.

I have two different domains that are connected via VPN connection through two routers. I can ping from domain to domain via IP address on clients and servers. However I can only do a net view command on...


This is an excerpt from a MS Technet page for error 53:
Resolutions: 1) if it is domain environment, check your WINS; 2) if it is peer-to-peer workgroup, enable NetBIOS over TCP/IP; 3) make sure the machine is running; 4) make sure file and Printer Share enabled on remote computer; 5) make sure client for ms networks is enabled on local computer; 6) make sure you type the correct name. 7) Make sure no firewall running or any security setting.
Pay close attention to #s 4 and 5 - I suspect XP pro might not be open enough.

Remote Desktop via VPN problem


Make sure that the Active Directory setting for the User you are using to RDP with (LDAP FQN) has the remote access option turned on.

Also make sure that the PC's you want to access have static IP addresses. Not sure if that was mentioned.

DELL --- Entrust/VPN - 1664


This is a known issue with Entrust, and normally happens if your communication via VPN is not using the IKE over TCP. Please select it. Also if necessary replace the ini file of Entrust, corruption of the ini file is known to cause the same error.

hope this helps if it does please rate it.

Unable to get remote desk top computer to work on acer aspire one


I think you're trying to connect to your office computer from home/somewhere else.

If that's the case, make sure you have done the following :
  1. Your VPN Session is connected
  2. Your Office IT Administrator allowed RDC over VPN
  3. Your Office Computer RDC is enabled
  4. Your User (local or domain user) having administrative rights or allowed to connect to RDC session
  5. You got no firewall blocking RDC connection or remote registry
To check if you already connected to your office VPN, launch command prompt and try pinging your office computer name or IP Address. As an example if your office computer name is PC-100 and IP address is 192.168.1.100 then you will issue : ping PC-100 or ping 192.168.1.100. If you got ping reply than you're good to go.

To Enable RDC on your office computer there are 2 ways :
1. On your office computer, right click my computer > properties > Remote > Enable Remote Desktop
2. Via remote registry :
- Start > Run > Regedit > Enter/Return
- On registry editor, go to File > Connect Network Registry > Type in your office computer name > OK
- On your office computer registry, browse to : HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server, find the key "fDenyTSConnections", double click it and change the value to 0

You should disable your windows firewall or 3rd party firewall for easier configuration. You can;however set up exception on your firewall but will need some knowledge to do that.

Hope it helps.
