Script to Open a batch file on a remote computer

I currently manually open a Remote Desktop and run a .bat file by double clicking it. I have found the following code on this site or maybe elsewhere that should allow me to automate this. This code works when I try to open Notepad or calc on the remote computer, but it wont run my .bat file. I get "process could not be started due to error 8". I checked and error 8 means "unknown failure". PSEXEC is not an option for me. Any help would be appreciated. Thanks.

Const ForAppending = 8
Const NormalWindow = 5
Set fs = CreateObject("Scripting.FileSystemObject")
Dim CurrentDate
CurrentDate = Date
DateTime = CurrentDate & "," & CurrentTime
