Incorrect DNS ip address entry in the Network Card properties

Here is the situation.  For a bout a month now 2 laptops and a PC in my network are showing the following simptoms, not all the time but every week or so this machines will boot and the user will call saying that their email is not working (Outlook-Exchange 2003), an ipconfig /all command shows that the NIC has the following values

100.10.10.50  IP
255.255.0.0  MASK
100.10.0.1  Gateway

192.168.1.1  DNS   (corect entry should be 100.10.0.9)

The DNS server entry is wrong, after I issue an ipconfig /release and /renew I get the correct DNS entry and email works just fine.  Then a few days latter it happens again.

my DHCP server is serving the correct values other PCs get the correct entries.

One more thing.  Yesterday, one of the 2 laptops would not let go of the DNS entry 192.168.1.1  an ipconfig /release /renew did not fix the problem.  The only way to get rid of the entry was to manually assign the correct value.

Any ideas or help is welcomed

When you edit the properties of the NIC, there may be an additional entry for DNS in the advanced section. Click on the Local Area Connection Properties, then TCP/IP properties, then the Advanced button, then click the DNS tab. Do you see the 192.x.y.z listed in there? If so, remove that.

If that's still a problem, download a DHCP discovery tool, such as RoadKill's DHCP Find - http://www.roadkil.net/dhcpfind.html

This will tell you if in fact your DHCP server is handing out a bogus address - or perhaps you have a second DHCP server on the network.

Hope this helps,
