In the windows control panel:

If you are using Windows XP's Category View, select the Network and Internet Connections category otherwise double click on Network Connections.

Then right click on your default connection, usually local area connection for cable and dsl, and left click on properties. Click the Networking tab. Double-click on the Internet Protocol (TCP/IP) item and select the radio dial that says Obtain DNS servers automatically

Press OK twice to get out of the properties screen and reboot if it asks.

That option might not be avaiable on some systems

Next Go start run type cmd and hit OK

type

ipconfig /flushdns

then hit enter, type exit and hit enter

(notice that space between g and / )

"First find your DNS settings

 

Here is how you do this in Microsoft Windows XP or 2000

 

1. Go to Windows Control Panel

2. Go to the 'Network Connections' (or 'Network and Internet Connections' then 'Network Connections') section.

3. Find the item in this window that is your connection to the internet and double click it.

* If you connect though BT this may be 'BT Broadband'

* If you connect though a network it may be 'Local Area Connection'

4. On the 'General' tab of the window that appears scroll down until you see the 'Internet Protocol' item and double click it.

5. On the 'General' tab of the window that appears check which of the following is selected.

* Obtain DNS server address automatically

* Use the following DNS server addresses

 

Next check the Settings are OK

 

1. If it is the latter make a note of the two sets of numbers and search for them in the list on the right of this page. E.g. a known bad server is 85.255.113.194

2. If you find then in the list delete the numbers and change the setting to 'Obtain DNS server address automatically'.

3. If you don't find them in the list this may still be the problem so email the numbers to us using the contact form below and then change the setting to 'Obtain DNS server address automatically'."

This should hinder the log-in of the rootkit to `net.
