DHCP and DNS problem?

This is a difficult question. My XP is not working properly. DHCP and DNS are not working. Address Configuration IP manually I can connect, but DNS is not working. nslookup works fine, so it's not a problem of protocol or the network stack. I rebuilt TCP and winsock now. DNS does not work for applications. DHCP client services DNS are working. I tried with the wireless card, Ethernet card and cable dial. It's the same problem with them. I'm using a proxy Sambar installed on another machine and I can use Connect wonderful. I disabled (almost) all software to test. So it's not a server security, the problem of anti-virus. He suspected a spyware / adware intercept the network stack, but could not find anything. Any ideas?
