How to use net.exe in a Windows Service

I'm tyring to use net.exe within a Windows Service.< xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

The following code was found at:

http://msdn.microsoft.com/library/default.asp url=/library/en-us/cpref/html/frlrfsystemdiagnosticsprocessclassstandarderrortopic.asp

Process myProcess = new Process();

string[] args = {"z: /delete"};  //a previously mapped drive using using net.exe through cmd

ProcessStartInfo myProcessStartInfo = new ProcessStartInfo("net ","use "+ args[0]);

myProcessStartInfo.UseShellExecute = false;

myProcessStartInfo.RedirectStandardError = true;

myProcess.StartInfo = myProcessStartInfo;

myProcess.Start();

StreamReader myStreamReader = myProcess.StandardError;

// Read the standard error of net.exe and write it on to console.

eventLog1.WriteEntry( myStreamReader.ReadLine());

myProcess.Close();

This code always generates the error:

The network connection could not be found

I realize this may have something to do with the security permissions of the service, but I have no idea how to change them.

I know how to modify the ServiceAccount, which I set to LocalSystem.

Any info would be greatly appreciated.

Thanks
