Determine logged on user on a remote Windows machine

Question

Is there a way to determine who is logged on to a particular (remote) machine given the IP address (or the workstation name) of the machine?

• The machines in question are on an Active Directory Domain
• The user running the script probably won't have any special rights on either their local or the remote machine
• Operating system is Windows XP

Any programming language is fine but ideally

• VBScript (yeah I know)
• C#
• Java
• DOS Batch file

Answer 1

Difficult to do depending on the permissioning on the machine. One way is to query WMI on the remote machine and check the owner of the explorer.exe process.

Answer 2

PSloggedon from SysInternals will provide this from a batch file, however the user would require admin access on the remote machine. I doubt you can get this information without Administrator access.

Answer 3

You don't need admin access. Just use net apis. ask on news://194.177.96.26/comp.os.ms-windows.programmer.win32 where it's a FAQ
