SMTP Service on WIndows 2000 Advanced

[craizie11]

We currently have a web server that has two nics in it. One nic is external (internet) which has a gateway assigned to it, and the other nic is internal (no gateway).

We are using the computer as a SMTP Server also, and currently the SMPT Server uses the external Nic for dns resolution and sending out email. Is there a way we can force SMTP service to use the iNternal Nic for DNS Resolution, and if that fails then use the external. The reason for this is because we have more control over our DNS Servers and can respond to it much quicker.

If I understand what you are asking correctly, you should be able to set your internal NIC (LAN) to use your DNS servers, and then in the advanced properties of TCP/IP just set up DNS forwarders to your ISP's DNS servers. Then if a mx or web record doesn't resolve local the request should be passed on to your ISP's DNS servers. Hope that helps...

Jeff,

Thanks for the support. The issue is this: when the web server is given a command to send out an email, how can we make sure the server first uses the internal NIC( to resolve the dns record) before using the external Nic (ISP).

Does that make sense? I remember you could do it in NT using the TCP/IP Bindings, im not sure if that functionality is available under 2000.
