I have a DHCP Server assigning IP leases to NT Workstations. I added the option for ‘003 Router’ to the scope of my IP Address Pool so that clients were allocated a default gateway and could browse the Internet from their workstations. Worked fine if they put an IP address for the web site they wish (i.e. 220.127.116.11) to view but not when using web site names (i.e. www.microsoft.com
I added a ‘006 DNS Servers’ option to the scope with two IP addresses given to me by my ISP – this worked fine for clients and they could browse the web using correct web site names (i.e. www.microsoft.com
However, clients/workstations are now experiencing long delays (up to 5 mins) when accessing their mails through Outlook 97 which are held on an Exchange 5.0 server. As soon as the ‘DNS Servers’ option is removed from the DHCP server’s scope, clients no longer experience delays when entering Outlook. Even with the DNS option removed from the server’s scope and added to a Workstation’s TCP/IP’s properties – the same problem occurs. With no DNS specified, no lengthy delays.
Any help on why this is happening or how to prevent it would be much appreciated.
