<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Just an FYI on your new SonicWall (we found out the hard way): You can not have a mix of zones on the SonicWall with some relaying IP requests and others being server (as a DHCP) server by the SonicWall. This is good to know if you intend on putting wireless AP on it in a different zone. It is unfortunately an all or nothing; either all zones get served IP addresses or all relay requests for DHCP. <BR>
<BR>
Doesn’t sound like this is what you have dealt with here, but it is something that took us a LONG time to figure out. Our previous, “less capable” Fortigate did this without an issue. :-(<BR>

<FONT COLOR="#1F497D">In ipconfig /all, are they showing the correct DHCP server?<BR>
<BR>
I have seen in the past where somehow or 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. <BR>

</SPAN></FONT><FONT COLOR="#0000FF"><FONT FACE="Arial"><SPAN STYLE='font-size:12pt'>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 I ran IPCONFIG and found that the ip addresses for our internal DNS servers had been replaced by the ip addresses of our external servers provided by out ISP.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.<BR>
