How to lookup a user name and machine name using an IP address (on windows)

May 3, 2006 · 1 min read

If you need to find a username but only have an ip address, if you use active directory (AD) then you can use the following method to find out the username:

  1. At the command prompt enter the following command:
    nbtstat –a ipaddress
    Where ipaddress is the ip address.
    This will list the machine name using that ip address.
  2. Then run the following command:
    net view /domain:ad > somefile.txt
    Where ad is the name of the domain you want to search and somefile.txt is the name of the file to contain the output.
    This will generate a list of every machine and who is logged in. 
  3. Open the output file and search for the machine name determined in step 1 (the username will be listed next to this).
