Remotely Retrieving Registry information

[Guest_imported]

I am wondering how I could get the registry on a remote computer across the network through dos. I know that I can type this in dos to get my information saved to a text file, but how do I do it on someone else's computer (assuming I have admin rights):

c:\> regedit /e c:\report.txt HKEY_LOCAL_MACHINE

Is there another piece of information that I can input into the command to have it report another computer?
