I have a NT 4.0 server with SP6A. I am trying to upgrade some exisiting AT&T application software. I am receiving the following error when trying to upgrade. "The ODBC Manager or Administator File is locked. Please close all applications and run setup again." I have no other applications running. I have also stopped all services. I have even set all services to disabled and rebooted server and still receive the same error. AT&T is telling me to uninstall the application and also the OS and reinstall everthing. Is there any way around this?
