windows service uninstall

Question

Hello,
i am assigned to work on a windows service developed by another programmer. I am having problems attaching to the windows service. the service was communicating with a remote server and for testing purposes, i want it to work on my local host.Whenever i get disconnected from LAN, it won't run probably because it can't make a connection to server, but i want to insert a breakpoint right at the beginning so whenever i find a connection to remote server, i change it. this didn't work,
so i thought of uninstalling the current service and installing a new instance of it with local host only, But i am having the following probs.///i don't know the exact path. solution (folder)has been pasted to another location

c:\Program Files\Microsoft Visual Studio 9.0\VC>installutil /u marketordermanage
r.exe

Exception occurred while initializing the installation:
System.IO.FileNotFoundException: Could not load file or assembly 'file:///c:\Pro
gram Files\Microsoft Visual Studio 9.0\VC\marketordermanager.exe' or one of its
dependencies. The system cannot find the file specified..

i don't have it in controlpanel\add or remove programs...

i even tried the sc command, it didnt work. how do i delete this service.

thanx inadvance
