other a firewall, wireless router, etc either gets added to the network by a
well-intentioned but poorly informed user, or somehow modified or goes back to
a factory default setting with DHCP server turned on. Sometimes the
workstation determines that it is getting DHCP from a bad source, so it goes
back to get an IP from the authorized DHCP server but it doesn’t update
the DNS server list with the info from the authorized DHCP server. You
end up with a working IP address, but bad DNS servers. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 color=blue face=Arial><span style='font-size:
12.0pt;font-family:Arial;color:blue'>On Monday afternoon a number of my DHCP
clients started losing their connection to the servers on our second
campus. We have a mapped “I” drive for a shared resource on
our Windgate campus. The first computer I checked would not map the
“I” drive when the user logged into the domain. She was
unable to even browse to the server shares. I ran IPCONFIG and found that
the ip addresses for our internal DNS servers had been replaced by the ip
addresses of our external servers provided by out ISP. This was the
situation on every problem client but not everyone has been affected. I
have a workaround but am more interested in finding the reason for problem as
well as a permanent solution. We have been using this configuration since
January 2003.<o:p></o:p></span></font></p>
