I would check my ARP table to determine it's MAC address, and then consult the MAC tables in my switches to determine what port it's plugged into, which would tell me whose computer it is - or, provided you have reverse DNS setup, you could do nslookup -type=ptr 10.1.168.192.in-addr.arpa. to get it's name

echo @echo (Alt-7) >beep.bat

The (Alt-7) is holding down the ALT key while pressing the 7 key on the numeric keypad.

That will create a batch file that beeps.

I forgot to mention, your batch should be

echo :loop>beep.bat
echo @echo (Alt-7) >>beep.bat
echo goto loop >>beep.bat

that way it continues beeping. Copy the file to the remote PC and use a remote command util such as psexec to execute it remotely.

if you have remote control, you could eject the CD drive as a visual pointer to the PC.  Start.. Run.. mstsc

- or get media player running...

I tried use net send /domain:<computername> it doesn't work, only beep once.

I have no reverse DNS setup, can not find the MAC address.
X:\>nslookup -type=ptr 192.168.0.12 in-addr.arpa.
*** Can't find server address for 'in-addr.arpa.':
Server:  dc1
Address:  192.168.0.30

And I can not remote control that PC, all I can do is ping and get an IP address.

Can you use your routing and switching infrastructure to tell which port its plugged into on the patch frame which would point you to a cubical?

Ping the IP address, now the MAC address is in your PC's ARP cache, check the ARP cache to get it's MAC address.
Q:\>ping -n 1 192.168.1.10

Pinging 192.168.1.10 with 32 bytes of data:
Reply from 192.168.1.10: bytes=32 time<1ms TTL=128

Ping statistics for 192.168.1.10:
    Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms

Q:\>arp -a 192.168.1.10

Interface: 192.168.1.55 --- 0xb
  Internet Address      Physical Address      Type
  192.168.1.10          00-04-23-ae-cb-5e     dynamic

...once you have the MAC address your switch will tell you which port.

Yup, and if its a cisco switch...

switch# show mac-address-table address xxxx.xxxx.xxxx  (xxxx's = mac address)

You'll get the port if you're on the switch that has it or you'll get the cross connect port to the next switch.
