    Hi,

    1. Connect to VPN from your desktop.

    2. Try to to ping SAP server with hostname .

    If your system is not able to resolve the hostname, try to add the entry in hostfile.

    Once above done, tyr to access the WEBDYNPRO.

    Thanks

    Anil

      Due to security reason ping may be disabled. I suggest you must telnet the specific port to check whether the ports are opened or not.

      from VPN desktop do

      telnet <yourserver> port (ex. telnet 10.10.28.99 50000 & make sure the same works on your server to confirm that you are testing the correct port) if you get a blank screen mean your port is opened and you should be able to access the UR else you will get an error mean you must request network team to open the port.

    Hi,

    As you mentioned above it seems its only netowork issue.

    Check below:

    1) Server hostname is mapped in local PC inclusing FQDN

    2) URL is bypassed from proxy if required

    Regards,

    talk to your VPN administrator. make sure that IP port used by web dynpro is opened for usage in VPN config.

    Hi Satheesh,

    In addition to Eric's suggestion, Please check with your Network Team for VPN configuration...

    You should check what network configuration you got when connected to VPN Server.

    Like IP Address, Gateway, and Most important DNS server.

    Just run command prompt and give "ipconfig /all" command. Check if PPTP Adapter has correct DNS server assigned...

    (I' afraid, you may not getting DNS server address for PPTP adapter after connected through VPN. As a result, name resolution is not happening and you are facing problem while accessing WebDynpro)

    You should be able to resolve SAP Server hostname when connected through VPN, same as you are on local network.

    For that PPTP adapter should get DNS server configuration which can resolve SAP server hostname to IP Address.

    Regards.
