DNS Problems with private address after server restart 1

[MattSavage]

Hello everyone!

I have a windows 2000 sbs functioning as our company's PDC. It has 3 NIC cards, 2 with public addresses and 1 with a private address. It also functions as our mail server, and the MX record points to mail.domain.com. I also have 2 host records named 'mail' for each of the public addresses.

I have found that when I restart the server with the private address NIC enabled, a DNS entry for our server is added with this address, which makes sense. However, after this occurs, we cannot receive incoming mail, because our host mail.domain.com cannot be resolved.

To fix this, I disabled the private NIC, deleted the dns entry, and restarted. After the restart, I enable the NIC and everything works fine, as long as that DNS record is not there.

Can anyone explain to me WHY this happens? Is there anything I can do to fix this, besides disabling/enabling manually???

Thanks!!

Uncheck the "Register this connection's addresses in DNS" checkbox in TCP/IP advanced properties for ths NIC and your problem should be fixed.

I will try that Serbtastic, thank you. I am sure that will work. I would still like to know why this causes a problem though, just for my own knowledge. If anyone can enlighten me, I would truly appreciate it.
