Im having an issue where the nslookup returns wrong ip address for some domains.

I have created forwarders, I have renamed netlogon.dns and netlogon.dnb and restarted the netlogon service. I ran DCDIAG on my SBS2008 server and goto the following results:

Hello,

First things first, open the SBS Console and run the Fix My Network wizard, if you're missing records it may be able to resolve it.

Also, why did you change the netlogon?

Does adding a dot to the end of your nslookup query (in other words, querying domain.com. rather than domain.com) make a difference? If so, this could be happening because nslookup is appending a suffix to your query and getting a wildcard record, if one exists, as a response.

I'm assuming these are external domain names that are resolving to bogus addresses. If you're using forwarders, query them directly with nslookup. From the nslookup prompt, type server forwarder_ip to change the server you're querying, then issue the query again. Do this for each forwarder and see if one or more of them return the incorrect addresses. If so, you should remove that server as a forwarder (or remove all forwarders and use root hints, if you prefer).
