When running KEPServerEX V4 under the System Account on Windows XP or 2003 Server, users must ensure that the service has been enabled to run on the desktop. When utilizing Console logins with terminal services, only one user can open it on the desktop. Finally, when running the server as a service under a different user account, users will not be able to open it because Microsoft disables it from the desktop automatically.
