Remove a VPN connection in Windows 7

In Windows 7 you an create VPN connections for PPTP, L2TP or SSTP. To delete a connection you can not just right click and press delete. But it’s still very simple, but a lot of people can’t find where you can remove VPN connections, because it is a kind of hidden ;-).

  1. First open Network and Sharing Center
  2. Click Change Adpater Settings on the left side
  3. Now you can see all connections and you can remove the VPN connection

DirectAccess for SMB and Lab environments – Design, Step by Step and Troubleshooting Guide

DirectAccess for SMB and Lab Environments This is a modified document which I wrote for a Microsoft Workshop at KTSI. It’s a Desgin, Step by Step and a Troubleshooting Guide for Microsoft DirectAccess. This is made for SMB or LAB environments not for Enterprise Deployments.

I hope this guide can help you deploy DirectAccess in your environment and you can enjoy DirectAccess like I do ;-)

DirectAccess Deployment done

Microsoft DirectAccess

In the last 3 weeks we had do some little Windows Server projects in a Microsoft Workshop at KTSI. Since I was really interessted in Microsoft DirectAccess as an alternative to “legacy” VPN such as PPTP or L2TP, I made a little project out of that and installed DirectAccess in my LAB. And I also created a documentation step by step documentation for LAB and SMB installations of DirectAccess.

I had some respect of the installation of DirectAccess and the requirements of DirectAccess. But to my surprise after the first try everything worked fine. So if you do everything step by step and pay attention to the details you will succeed.

Now to DirectAccess, it’s not just another VPN technology. It can save users and the IT deparments a lot of time. How many hours do you have spent do troubleshoot VPN connection problems? Now with DirectAccess users can work with their notebooks as they were within the company network. You don’t really care about firewalls or connection losses.

But more on DirectAccess later, I will post the step by step guide later this week.

Windows PPTP VPN with Cisco Linksys RV042

Cisco Linksys RV042

Today I was setting up my little lab, I decided to create a Windows PPTP VPN for my lab network which should give me more comfort. First I installed the Network Policy and Access Services Role and did the configuration. I also enabled PPTP Passthrough, added a port forwarding and a firewall rule to my Cisco Linksys RV042. I know the RV042 is not really a big deal, but you have a lot of jobs and if you don’t really need a lot of network options, like me in my lab, this is a pretty cool device.

I now tested the VPN Connection with my Windows 7 Client. Error 800 and 807 which basically means no connection through the firewalls with the VPN Server.

I checked again the Firewall Configuration on my RV042, and could not found any mistake. After a quick search with Google and Bing ;-) I saw a lot of posts with the same problem and the Linksys RV042.

After some search I came to a solution, I deactivated the SPI Firewall on the Device, and this caused the problem. After activating the SPI Firewall again, the error was gone and the VPN worked.

  8. Open Ports in your FirewallFor PPTP: 1723 TCP 47 GRE
    For L2TP over IPSEC: 1701 TCP 500 UDP
    For  SSTP: 443 TCP

Optional: If you don’t have a DHCP Server in your local network you have to add a static address pool. This could be if you have a stand-alone Server by your provider.

  1. Right click on “Routing and Remote Access” and open Properties
    Add Static address pool
  2. Click on the IPv4 Tab and check “Static address pool”
    Add Static address pool
  3. Add a static address pool of private IP addresses
    Add Static address pool
  4. Add secondary IP Address to the Server network interface which is in the same subnet as this pool.
