Regmon.exe Regmon is an application that monitors and displays all Registry activity on a system.
Tcpview.exe TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the owning process name, remote address and state of TCP connections.
Tdimon.exe TDImon is an application that lets you monitor TCP and UDP activity on your local system. It is the most powerful tool available for tracking down network-related configuration problems and analyzing application network usage.

MD5sum.exe Print or check MD5 checksums.
PromiscDetect.exe Checks for possible sniffer activity on the local box
Nc.exe (Netcat) utility which reads and writes data across network connections, using TCP or UDP protocol. It is designed to be a reliable “back-end” tool that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities.
Dumpreg.exe Somarsoft DumpReg is a program for Microsoft Windows that will dump registry values in an easy-to-use listbox. Options include finding all registry key or values whose name or data matches a specified string, filtering so only the matching items are shown, copying to the clipboard, printing. For Windows NT, the time of last modification is shown and there is an option to sort by time, which makes it easy to find recently modified registry entries. 
DumpACL.exe Somarsoft DumpAcl is a security auditing program for Microsoft. It dumps the permissions (DACLs) and audit settings (SACLs) for the file system, registry, printers and shares in a concise, readable listbox format, so that holes in system security are readily apparent. DumpAcl also dumps user, group and replication information. DumpAcl is a must-have product for Windows NT systems administrators and computer security auditors.
MD5.exe Integrity file checker – gets the hash of a file and after transport to ensure image integrity
DD.exe dd reads and writes data by blocks, and can convert the data between formats. dd is frequently used for devices such as tapes which have discrete block sizes, or for fast multi-sector reads from disks. The conversions can accommodate computers that require de-blocking, conversion to/from EBCDIC and fixed length records.
