Windows Server 2003 - Running a service as a Local System account.

I have a service that was written in VC 6.0 under Windows Server 2003. It
has a GUI and an icon that I place in the task tray. Double clicking the
icon displays the GUI. The service is set to start automatically and run
24x7. I had to add a feature to the service to periodically copy files from
another machine for failover purposes. Unfortunately it cannot access the
other machine while running as a Local System account and will not "allow
interact with desktop" if running as a specific user account. I know a
service with a GUI is not ideal but before I spend the time (which I don't
have) to decouple those parts, is there a method I could run a batch file or
process as a specified User and achieve my goals?

I have tried the following but can't get the CreateProcessWithLogonW to
succeed with correct values:
 // load the administrator profile
 DWORD dwLogonFlags = LOGON_WITH_PROFILE;

 PROCESS_INFORMATION ProcessInfo;
 STARTUPINFOW StartupInfo = {0};
 StartupInfo.cb = sizeof(STARTUPINFOW);
 StartupInfo.dwFlags = STARTF_USESHOWWINDOW;
 StartupInfo.wShowWindow = SW_SHOWNORMAL;

 // go do it!
 if (!CreateProcessWithLogonW((LPCWSTR)wszAdminName,
  (LPCWSTR)wszDomain, (LPCWSTR)wszPassword, dwLogonFlags,
  (LPCWSTR)wszApplicationName, (LPWSTR)wszCommandline, 0, NULL, NULL,
  &StartupInfo, &ProcessInfo))

TIA.
