    Unplug all network cables.

    If this is not a suitable solution, could you give us just a teeny hint which OS it is, and how you connect to the internet

      Re: Port 5190

      thanks for your responce...

      I install the security configuration wizard

      its windows server 2003 r2 with service pak 2
      this server is running server 2k3, exchange and dns
      The server has two NIC one internal and one external

      i was considering moving to 2008 within the next two week but until then...

      once i install the program and turned off ports 5190 135 and 445 from the outside world it seems fine

      but i have another issue

      please see attached, please give me your thoughts


      thanks

        Re: Port 5190

        Isn't it protected by a firewall? And why does he has 2 NIC's?

          the server is running exchange, does not exchange need direct access, in front of NAT??, I gather from your comment that there should be no public ip address on this machine??,

          The problem exist how do i correct it??

            Exchange definitely does NOT need direct access!
            If you are just using it to send / receive emails, all you need is port 25 forwarded on your router / firewall
            If it is providing OWA you need port 443 open as well

              thank you for your response,

              its is protected by a firewall, but about 2 months ago, we need to open all ports to test an application. and my network person did not lock down the network. such is life

              thanks for all your input

              thanks

                Re: Port 5190

                Never ever open all ports because of testing...
                Testing should preferably done in an isolated environment.

                Exchange doesn't need direct connection before the NAT devices. It can perfectly be placed behind a NAT device.
                There are multiple ways to configure exchange behind a firewall. It depends a bit how many public ip ranges you have and how many addresses you have

                I also believe it's a DC am I correct? This since I can perfectly RDP towards your server (sorry but I needed to test it...)
                Also running exchange on a DC is also not supported
                I suggest you remove the attachment or at least that you edit your public IP addresses.

                  Your network person needs to be sacked.

                    thanks for you input, life is a learning experience,

                    things were done to expediance and this always causes problems but sometimes you have no choice

                    as for running exchange on mu dc, when funds are tight you do what you have it and it was one hell of a powerful box, it could have run much more. but in the next few week i am moving to win 2008 with 4 seperate servers and the problem should go away.

                    Again thank for all your input
