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 aa c Adds a static entry. > arp -a.... Displays the arp table. 4 Bonus Commands Bonus Commands (13 slides)CTEC 110

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. Bonus Commands (13 slides)CTEC Bonus Commands

regedit – Registry Editor System configuration information is stored centrally in a hierarchical database called the registry. You can use Registry Editor to add and edit registry keys and values, restore the registry from a backup or to default values, and to import or export keys for reference or backup Bonus Commands (13 slides)CTEC Bonus Commands

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