We're trying to implement a custom solution for Growl for Windows. We tell the Growl client to subscribe to notifications from our server. The server then gets a message from the client via the GNTP (Growl messaging protocol). We require the name of the user logged into the client machine in order to do database lookups. The GNTP does not provide this information.

So, we have a connected client socket (and thus, IP address) and a message from this client containing its machine name.

Is there any possible way to determine the username of the user who is logged into the specified machine? We have access to windows domain services.

A: 

This will give you the Windows domain and current user (if that's what you're after)

using System.Security.Principal;

        if (WindowsIdentity.GetCurrent().IsAuthenticated)
        {
            string Result = WindowsIdentity.GetCurrent().Name;

A: 

We ended up doing the reverse (sorta) by having a client-side application run at logon and let our server know which user had logged in.
