  • Slow connections

    Hi,

    Ive recently built a small windows 2003 domain with a Exchange 2003 server. Everything is working fine apart from one small problem. When the clients (Outlook 2003) connects for the first time, it takes around 3 minutes before it establishes a connection with the server.

    Im able to ping the server from the desktops without any issues and Im also able to browse shares on the exchange server without any problems.

    Ive removed all virus software (sophos) from both client and server but this made no differences (Ive reinstalled sophos now).

    Any ideas?

    That looks like classic name resolution problems. The client is timing out and then using broadcast.
    Make sure that you have DNS on all machines configured to use the domain controller ONLY for DNS. No external DNS servers should be in the network configuration of any machine.

    Simon.

      Simon, thanks for stopping by.

      Ok, so every client machine needs to have its dns pointing to the - lets say the domain controller which is also the exchange box, then set the dns on the exchange server to the external dns settings of our isp?

        What I said was "No external DNS servers should be in the network configuration of any machine. " That includes the domain controllers.
        If you need to use external DNS servers of your ISP then those should be configured as forwarders in the DNS Server applet on the domain controllers.

        AD relies on DNS to work correctly. Your ISPs DNS Servers are not AD integrated for your domain, so will not have the information that an AD member requires to find the domain controllers and work correctly.

            Result!!

            When setting the dns, it was obvious I had the wrong bl00dy address in the secondary dns setting on the clients. Now that it has only one ip address which is the dC, no more connection issues.

            Many thanks Sembee
