VBS to start a process on remote desktops

I'm looking for a script that logs into a remote desktop using proper user credentials and start a process, say notepad.exe.

I googled around and found the following script:

Code:

---

strComputer = "webserver"
Set objWMIService = GetObject _
    ("winmgmts:\\" & strComputer & "\root\cimv2:Win32_Process")
 
Error = objWMIService.Create("notepad.exe", null, null, intProcessID)
If Error = 0 Then
    Wscript.Echo "Notepad was started with a process ID of " _
        & intProcessID & "."
Else
    Wscript.Echo "Notepad could not be started due to error " & _
        Error & "."
End If

---

The problem is, I need to incorporate the username and password somehow to log into "webserver" in the code in order to even use GetObject method. Any ideas?

Thanks in advance! :)
