DNS poisoning

[strueson]

I have a win2k3 DC that is also the primary DNS server for the workstations. Every 2 or 3 days DNS gives back wrong information for external websites so the users get redirected to a wrong page.
The only why to fix the problem so far is the stop and start the DNS service.

Any idea?
Thanks

strueson,

Try this solution:
1. Go to Start > Control Panel.
2. Click Performance And Maintenance, and click Administrative Tools.
3. Double-click DNS.
4. In the console tree, select the applicable DNS server.
5. Go to Action > Properties.
6. On the Advanced tab, select the Secure Cache Against Pollution check box in the Server Options section, and click OK.

Try different DNS forwarders

Have you also ruled out malware on the clients editing the local hosts file causing the misdirection?
