There are SO many possibilities here.

1) The machines in DomainB could be set so that they do not appear to the
browser (and hence, wouldn't show in Network Neighborhood). Check registry:
HKEY_LOCAL_MACHINE\\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameter
s\Hidden value of 1 = true, and thus, hidden - keeping it from the browser
service.

If so inclined, you can statically map those computers in DomainB:
START, FIND, COMPUTER then type in computer name, click FIND. Once the
computer is found, drag it to Network Neighborhood window, click YES to add
shortcut.

Just two ideas. There are more. But the easiest is to first contact
ADMINB and ask what the settings are there.

hope something helps....
