I assume you are having a problem with Name Resolution. Can you "ping" the
machines by IP address but not by Name? Then you must resolve a method of
Name Resolution for YOUR network. Look for a file on each system called
HOSTS. Open it up in notepad. Read the instructions. Edit the file and save
it.
OR map drives by IP address i.e. "netuse Z: \\10.1.1.10\share"
