when work, I need three or four computer access each other(i.e. shared file),
one is vista os, one is xp, and the other two is w2k3. Most of time, vista
can't connect with others, but on accasion it can connect with others. It
looks like it is dynamicaly wheather can connect with others. I also want to
find the wizard of 'add network place' which XP OS has, but there can't find.
Is there someone can help me, it is a really much trouble for my work.
