Here is an all-in-one program I fell in love with a while ago.
With WS_Ping ProPack you can:
Verify connectivity to a particular device on your network
Quantitatively test data connections between your computer and a remote system
Trace the path to a network host or device
Obtain information on host names and IP addresses
Scan your network and list devices and network services
View summary information about a network host or device including the official hostname, IP address, and contact information (from the Whois database)
View Simple Network Management Protocol values as well as Windows network domains, hosts, and workstations
Search information (such as user's full names and e-mail addresses) available through LDAP
System Requirements: Intel 486 or Pentium processors with Windows (95/98/Me/NT/2000/XP).
