Hi All, I know this problem is not related to Exchange, but any help from u guys will be appreciated. We have a windows 2000 domain controller. DNS is configured on this.. We want to use software called Group Mail for sending Bulk emails. That software looks for the internal DNS server for the MX records lookup for the domains. But when we run nslookup on the internal server, it says DNS request time-out in 2 seconds. Although we had removed (.) zone from the forward lookup zone. And we had setted the forwarders on the DNS server the DNS IP address of the ISP. But if in the Group mail software settings we use the ISP DNS IP it works. Please help us out in this matter. ps. check out our latest product: www.DriveInside.com - India's No. 1 Auto Website -------- Amit Kapoor Network Engineer Module One India Ltd.
