I have a Windows 2000 Server. It is set up with two NIC's. One is connected to a cable modem the other to a hub.
I have Microsoft Proxy Sever 2.0 on the server with SMTP Services installed.
I have had to disable DNS services on the server as when I try to send an email from a workstation, it tries to resolve from the server's DNS. I am not a networking expert but I believe that this is the reason my emails are ending up in the badmail folder. Is there something I'm missing in the setup ofthe server which would allow me to use DNS on the server and still allow the workstation to send email?

Hi robw,

i guess you have an Exchange Server as Emailserver. On the other Hand you would have vonfigured the IMC for delivering the E-Mail to an Host (Your Proxy Server) since their are SMTP-Services, however. The other reason for your Problem could be, youre right, the DNS Service. I hope you have configured it right, like you installed it as an forwarder ? Not ? OK !
Let me try again:

Since your using w2k as your favorite NOS, you must use DNS for name resolution. Normaly their are twomethods, depending on your environment. The first is you going to split the DNS Naming convention in two separte parts, Inbound and outbound. You create a new Top-Level Zone like .INTR for your intranet, their you create your Domain like MyHome.intr. Now every Time the client is searching for Ressources in your intranet it knows that the Service is inbound and connects only to your inbound Server. If you have service in the Internet, your users have to remember to diffrent adresses.

But most people like the straight way and one naming convention. It?s much easier for your users, but not for U.

I know here is not the answer you need, but give us a chance and give more information about how you put the pieces togheter.

Exchange server does not exist so sync is not possible. Two outlook 2000 installs at two locations.

The wks with the internet connection should have at least one DNS Ip address defined (provided by your ISP provider)
From a command prompt (DOS), start NSLOOKUP.exe. This utility will connect you with the dns server defined in tcp/ip properties. Once connected, you should see the DNS server responding with it's name, and it's prompt ">"
Type SET QUERY=MX to query this DNS server for an email ip address, and then start typing internet domains, such as microsoft.com, novell.com and the dns should respond with its mail system's name and IP address. If not, double check your dns configuration with your provider.
Also be sure that your proxy is able to let "everyone in the network" to resolve dns, so try the same from the other machine, it should work.!

You had to configure the DNS-Server as an Forwarder to the Internet, then it should work.
