I just had exactly the same problem. I am using
mydomain.mycompany.com as my domain name. If I try to do nslookup on,
say, google.co.uk I get the IP address for
google.co.uk.mydomain.mycompany.com.

It appears to be that the client lookup is misbehaving. It treats
google.co.uk as unqualified label
Actually, google.co.uk is not fully qualified, for it to become fully
qualified, you have to include the root "." in the name as
"google.co.uk."(notice the ".")

rather than an FQDN and so tries to
qualify it by adding the domain suffix to it. If it finds the wierdly
qualified address, it doesn't continue to look up the unqualified
address and you get the wrong answer.

This is invisible and just slows down the DNS lookup UNLESS you have
an overzealous domain registrar who has added an entry for
*.mycompany.com to the DNS.

I just went to the domain registrar and removed that entry from the
DNS. Everything worked fine after that.
This is the correct move, and is probably easier than modifying the DNS
suffix search list to not include your public domain name.


If this isn't a bug in the windows IPV4 client can someone explain
why it is doing it, please

It's not a bug, it is by design and you're not the first to have problems
with the Wildcard record.
