How to Run FTS under NT without Administrator Rights

The information in this article applies to:

• Frontline Test System, version 1.5 and higher, Serialtest Async, Serialtest Spy, Serialtest MLT and SerialBERT Async for Windows NT 

·        PROBLEM DESCRIPTION

When starting FTS, you receive the following error message:

Your user name, [name here], does not have the "Load and unload device drivers" user right. Therefore you cannot run this program in "Live" mode. See your system administrator for help."

This message is followed by an FTS Fatal Error and the program exits.

SOLUTION

You must have Administrator privileges in order to load and unload device drivers. The device driver being loaded and unloaded in this case is Frontline's serial driver, which replaces the standard serial driver while FTS is running. If you do not have Administrator privileges, you can still run FTS by putting Frontline's serial driver in place of the standard driver and letting it be used as the standard driver. Frontline's driver is compatible with the standard driver and other serial applications should operate normally. 

Start Explorer, and browse to the C:\Winnt\System32\drivers directory. 

Find the file serial.sys, and rename it to serial_microsoft.sys, or some other name that will let you know that this is the standard serial driver. You may need to change the window options to allow you to see all the files in the directory. To do this, go to the View menu on Explorer and choose Options. On the View tab, click the "Show all files" radio button. 

Browse to C:\Program Files\Frontline Test System and copy the file serialnt.fts to the C:\Winnt\System32\drivers directory. Rename serialnt.fts to serial.sys. 

Reboot. 

Once NT has finished rebooting, Frontline's driver will be used by all applications, including FTS. When FTS starts up, it will see that Frontline's driver is already in place.
