  • Outlook Exchange no connection through vpn win7

    Hi,

    I have recently installed windows 7 prof and can't get outlook to connect to our exchange server 2003 via VPN.

    It works great when in the office and not having to use the VPN connection.

    VPN connection also works great, i can connect to our server without any problem. \\server01 works and i can copy/past files. I can also use our ERP system through the same VPN tunnel without any problem.

    VPN is setup as PPTP. We are not using a Domain!

    Does anyone have an idea how to solve my problem.

    Thanks in advance.

    Best Regards,
    Norbert

    can you ping the fully qualified name of the exchange server from the vpn workstation?

    Also - do you use Direct Exchange, or RPC over HTTP?

      Yes i can ping the server without any problem.
      We use direct Exchange, it works for other users with XP pro.

      I'm the first to use Win7.

        How can you be using Exchange without a domain? or do you mean the client PC is not a domain member?

          I meant the client pc is not a domain member.

          Again it works when being in the office when we don't have to use VPN.

              ndave, how about a full description of your setup so we don't have to play 20 questions trying to find out the necessary info to diagnose your issue. Just had that in another thread and it just gets annoying wasting time asking inane questions about info that should be supplied in the first post.
              1 1 was a racehorse.
              2 2 was 1 2.

                check that all the appropriate ports are allowed to communicate between the vpn subnet and the corporate subnet.

                This would include the LDAP ports, as well as the exchange ports, and RPC endpoints.
                I'm not going to tell you what they are - you should either know, or be able to find out yourself...

                Is this a laptop or a workstation?
                If it's a laptop (or even if it's a workstation) take it into the office physically, and attempt to connect to outlook there.

                  What firewall profiles are you using? As this isn't a domain member PC you won't have a domain profile, but if in the office it's on Private and out of the office Public that'd stop it connecting.

                    Re: Outlook Exchange no connection through vpn win7

                    Hi Guys,

                    I have Firewall disabled for each (for test) profile.
                    I was using Outlook 2007 and am now using Outlook 2010 (both did not work).

                    As discribed in the first post it is working when being in the office physically and not having to use VPN.

                    For VPN i'm using PPTP.
                    I believe all ports are open because i'm not using any firewall on my laptop.

                    What would you like me to discribe about the vpn?

                      Re: Outlook Exchange no connection through vpn win7

                      If the VPN is router to router, it may not open all ports
                      Can you give an indication of the hardware used to set up the VPN

                      Any reason you cannot set up RPC/HTTPS on your Exchange server and bypass the VPN completely?

                        Re: Outlook Exchange no connection through vpn win7

                        Hi Ossian,

                        We will give that a try.

                        Router is a D-Link DFL210 with all ports opend to and from trusted VPN users.

                        I now have an idea where to look for.

                        I will post again if solution is found.

                        thx

                          Good luck!
                          Lots of links on the main site www.petri.com about RPC/HTTPS on Exchange 2003
                          Its worth getting a commercial certificate from GoDaddy or similar -- cost will be about $30 per year

                            Ok, we found the problem.

                            I used Windows XP and edited the hosts file to connect to the server lik this.

                            192.168.100.200 server01

                            This was enough when using XP but somehow with Windows 7 i had to add the full hostname of the server like this.

                            192.168.100.200 server01
                            192.168.100.200 server01.companyname.local

                            After adding this and restart of the machine i'm now using Outlook 2010 on Windows 7 with our exchange server through VPN.

                            Thanks for your help.

                              So you have a DNS problem at the remote site
                              Where / how do clients pick up an IP address when away from base?
