In the morning, when users begin work, sometimes the Internet will be very slow or down for 15-30 minutes. It usually comes back up again, but we continue to have slow downs that last for several minutes throughout the day. If we restart our server, the problem goes away for a awhile.
Here is the setup.
Internet is static DSL coming into a Linksys Business Router
Router assigns IP addresses
Static DNS addresses for the WAN side supplied by Verizon
LAN DNS is Windows Server 2003 SMB address
Main Server is SMB03
Second server is Windows Server 2003
15 XP pro clients
Question: Could my DNS setup and DHCP setup (using router) be the problem here? If so, what should the setup be?
