Question : Problems with Domain/DNS

We are having a weird issue.  I have a laptop that is joined to our domain.  I am planning on taking this home/on business trips.  The issue is that when I try to access another network other than our domain, it seems like there is a weird DNS issue or something blocking it.  I get ip addresses from the other networks, and can ping ip address like google and such, but cannot browse.  I disjoined the laptop from the domain, and this corrected the problem.  So my guess, there is an issue with the domain or a group policy object?  

Answer : Problems with Domain/DNS

this is crazy...
what does ipconfig /all show when you are connected to the domain, connected to wireless (as you just described), or out of the domain
when it's not working can you still ping outside addresses (like 69.147.114.224 for yahoo.com)?
what do you get when typing nslookup at the command line?

check the group policy, is there anything useful? what about event log - anything show when you're off the domain?
