Hello to everyone! Is there a dos command that will display ALL the ip address connected on the LAN? Thx for ur help!

Not in W2K3 as it has no MS-DOS, it does have COMMAND PROMPT like W2K/XP though: http://www.ss64.com/nt/

plainandsimple, You need to get off of that bandwagon. W2K3 does come with DOS, it's just not normally used. The command prompt is started with CMD.EXE, but MS-DOS is started with COMMAND.COM. According to Microsoft's knowlege base command.com is still included with W2K3, but if it's missing or damaged, it can be re-installed from the W2K3 CD. http://support.microsoft.com/kb/305521 Here's a listing from Microsoft's TechNet of other MS-DOS commands included with W2K3. http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/ServerHelp/e3799c45-a9b5-4ef8-a97d-987813291307.mspx Chcp Diskcomp diskperf diskcopy doskey format label mode print prompt recover rmdir sort xcopy I'm sure there are others, those are the ones that they made changes to their functionality.

Search for Angry IP Scanner and download it. You enter the range of your network IP addresses, and it returns the status of each, including whether each IP is "alive" and what machine is using each address.

ping the subnet by pinging xxx.xxx.xxx.255 then do a arp -a You will see a list of ip addresses which are what ping found and populated your arp table with. Golly gee wilerkers everyone! Learn to Internet Search

..but MS-DOS is started with COMMAND.COM ?? Actually if you go back to NT4 it is really NTVDM, aka New Technology Virtual DOS Machine, aka an emulator...........

M$ now call it a "16-bit MS-DOS subsystem" MS-DOS up to version 6 was an Operating system in its own right, therefore will give a full explanation in future. But it is still not Standalone MS-DOS par-se.
