arp - Displays and modifies the IP-to-Physical Address translation tables

ARP -s inet_addr eth_addr [if_addr]ARP -d inet_addr [if_addr]ARP -a [inet_addr] [-N if_addr] [-v]

-a Displays current ARP entries by interrogating the current protocol data. -v Displays current ARP entries in verbose mode. All invalid entries and entries on the loop-back interface will be shown.-d Deletes the host specified by inet_addr. inet_addr may be wildcarded with * to delete all hosts.-s Adds the host and associates the Internet address inet_addr with the Physical address eth_addr. The Physical address is given as 6 hexadecimal bytes separated by hyphens. The entry is permanent.

Examples: > arp -s 157.55.85.212 00-aa-00-62-c6-09 .... Adds a static entry. > arp -a .... Displays the arp table.

msconfig – Microsoft Configuration Tool

System Configuration is a tool that can help identify problems that might prevent Windows from starting correctly. You can start Windows with common services and startup programs turned off and then turn them back on, one at a time. If a problem doesn't occur when a service is turned off, but does occur when that service is turned on, then the service could be the cause of the problem.System Configuration is intended to find and isolate problems, but it's not meant as a startup management program.

Defrag - Locates and consolidates fragmented files on local volumes to improve system performance.

Syntax: defrag <volumes> | /C | /E <volumes> [/H] [/M | [/U] [/V]] defrag <volumes> | /C | /E <volumes> /A [/H] [/M | [/U] [/V]] defrag <volumes> | /C | /E <volumes> /X [/H] [/M | [/U] [/V]] defrag <volume> /T [/H] [/U] [/V]

Parameters:Value Description/A Perform analysis on the specified volumes./C Perform the operation on all volumes./E Perform the operation on all volumes except those specified./H Run the operation at normal priority (default is low)./M Run the operation on each volume in parallel in the background./T Track an operation already in progress on the specified volume./U Print the progress of the operation on the screen./V Print verbose output containing the fragmentation statistics./X Perform free space consolidation on the specified volumes.
