Hello. For remote computers getting the \"The network path was not found. (Error: 53)\", are you able to access these through \"My Network Places\"? Also, are you able to ping the remote computer by its name from a DOS Command Prompt?
NEWT works off the computer name when scanning. This is soley a Windows error, so if NEWT reports it, Windows should also report it when trying to visit it through \"My Network Places\".
Please let us know what you find out. We\'re here to help.
