I am having a bit of a problem between XP and Windows 7. Both laptops are members of the same domain. I have a share setup on both laptops. While connected to the domain network I can view the share in either direction. However after disconnecting both laptops and plugging them into a private network I am no longer able to browse from the XP laptop to the Windows 7 laptop. Windows 7 to XP still works.
I have completely disabled all firewalls.
Using to XP laptops everything works just fine with cached credentials. Is there a setting some on Windows 7 forcing the connecting laptop to use a domain controller for authentication?
