Did you know you can get any Windows computer’s MAC address without leaving your chair?
Hmmm. When I try it it wants a password from the computer I am on, Medion-PC. The legitimate password does not work.
Yeah, it's doing the same thing for me. I'm guessing it only works on a Windows domain, but we'll get @taygibb to let us know what the deal is.
Works fine for me. Window 7 64 bit
@xhi @geek use this if you are not on a Domain:
getmac /s viper /U administrator /P Viper$Replace username and password with those of an account on the remote machine. Soon as someone can confirm this also works for them ill update the article.
Also after some testing with @geek this doesnt appear to work with Microsoft Accounts, so you will have to use local creds.
This if I did it right did not work for me.
The computer I'm on has no user password for user xhi. The computer upstairs has user xhi with the password I typed.
@xhi Ok i read your post wrong at first. Change your username to upstairs\xhi
I actually got up from my chair and went upstairs to verify the password, lol. No luck yet.
@xhi LOL. What operating systems are you using?
I'm not having luck either, but I'm thinking I must have a setting wrong somewhere. I can't access the shared folders on that computer either.
I was on vista to a windows 7. But, I just went into my office and tried W7 to W7 and same result.
I wont lie here, i dont have any idea as to why its not working for you. However, the fact that it also works for @the1aitch leads me to suspect a config error.
@xhi The fact that you using the same name for both user accounts may or may not have something to do with it. Thats the only thing i can actually think of. @geek does your setup use the same names?
Tried it Windows 7 to a Windows 8 computer and got
Error: the RPC server is unavailable.
Have no idea what that is.
@xhi I just got the same message on one of my setups, i think i may be on to something.
@xhi OK as a test disable your firewall on all network profiles (if you are using the built in firewall) on the Windows 8 machine. Then try go from the Windows 7 machine to the Windows 8 machine like above, you shouldnt get an RPC error anymore.
Why don't we just use
arp? Sure, it takes two steps. But it's quick and fairly reliable. Ping the hostname to get the IP and verify it's up, then just
arp -a | find "xxx.xxx.xxx.xxx" (replace x's with the IP). No admin login required.
@Iszi Mostly because i didnt think of that. Also because i was using the technique i wrote apart as part of a much bigger project im working on.
5 points that though, its an awesome tip!
Just updated the article to mention that. Definitely simpler.
I figured out an interesting tip while testing.. I was pinging my desktop and it defaulted to IPv6. The ping command supports a -4 argument to force pinging IPv4 instead. So like
ping -4 PCNAME.
Turning off firewall got me back to password not recognized.
