Very strange DNS issue

[rkelley]

I have my laptop that is joined to my AD domain at work which is
corp.company.com

When I am plugged into the corporate network all dns resolution works fine.
now when i connect to a wireless network at home or anywhere else all
nslookup queries append corp.company.com onto the hostname or even fqdn that
I try to lookup.

For instance:
nslookup google.com
returns google.com.corp.sportchassis.com

also no matter what you lookup the ip is the same on the return and it works
fine if you put a . after the domain


Thanks

Is it possible your LAN domain name and Internet domain are the same?
Posting the results of ipconfig /all and nslookup here may help.

yes they are similar, my LAN domain is corp.sportchassis.com and my public
domain is sportchassis.com.

If this is really a problem then I will be really pissed because all of the
documentation for AD that I looked at and researched when we setup AD 5
years ago said it would be fine to have corp.domain.com as your AD domain
name. I will post results from the two commands shortly.

Thanks,
