We have the following setup currently running

Location A

Windows 2k Adv Server + 50 Cliensts (Windows 98SE)
Lan Ip Address - to
Gateway Ip      -

Router A Lan ip   -
            Wan Ip -

Location B

Windows 2k Adv Server+50 Clients (Windows 98SE)
Lam Ip Address  - to
Gateway Ip       -

Router B Lan Ip   -
            Wan Ip -

We have already connected both the location thru leased line with simple static routing .Now we have installed workgroup mail server in both locations for intranet mailing.We dont have registered domain names.We have chosen our won domain names as for location A and for location B.

Dns Server is up and running on win2k adv server at both locations.

Workgroup mail server error log show "performing dns lookup for failed"

How to properly configure the dns server so that workgroup mail server can resolve the domain names

Thanks in advance

    I take it those domain names are used for local delivery?

    You may be lacking an MX record for the domain. Open up DNS Manager on the name server used by the mail server. Then add two records:

    1. Address (Host) record for the mail server: mail  IN A <IP Address>
    2. MX (Mail Exchange) Record for the domain:  IN MX

    Now your mail server will know where to attempt delivery for rmkv to.

    You might also want to configure a Reverse Lookup zone [PTR records] as well..

    Local mails within the domain is being delivered correctly.Problem occurs only when mailed to the other domain.

    Win2k server,DNS,Webmail Server all are running in the  same machine

    I take it the mail server is responsible for mail delivery to both domains?

    If it delivers to another mail server then it needs to be able to find the MX record for the other domain in DNS. If it's all purely local then it needs to know that it's to accept mail for that domain.
