Our Domain controller is set to be the authorative DNS server on our LAN. We just moved to a new ISP with dynamic hosting for our web site and pop e-mail. We changed our DNS server forwarders o the new ISP's DNS addresses. Now it takes forever for a LAN user to log onto our domain controller. Any ideas why? EG__.____._

Thanks. We'll let you know when a new response is added.

Check a workstations IP information to see that is only points to your internal DNS server. Actually you do not have to use your IPS’ DNS settings. If you have not looked at OpenDNS (www.opendns.com) I recommend that you do. You can do many administrative things with their free DNS, like prevent IM sessiongs, logo the did not find page type things.
You can also check group policy to ensure that some setting is not holding up the process. BUT, I would concentrate on DNS to ensure that your workstations can find the resource records needed for logon (domain controller).
Best of luck
