All Rights Reserved Ok Satus : Win NT/2000 Platform : " Start menu->Programs->Administrative tools->Computer management-> System tools->System information->Software environment->drivers->Sentry". " Start menu->Settings-> Control Panel->Devices-> Sentry" For Win 20000 For WIn NT: 6. Under Windows 95, whenever a 16 bit application protected by Sentry Hardware lock runs, the ‘device conflict’ window pops up. Ok Satus : Win NT/2000 Platform : In most cases, this message appears only once, after you boot the PC, and if you select MD-DOS prompt in the device conflict dialog box, it will not appear again. This problem also can be countered by changing setting of VPD.VXD or by setting the print operation to "directly to port" instead of "spool" Resolution: Whenever you run the protected application, you access the printer port, which otherwise is acquired by windows print spooler or a similar process. In such an event access from the 16 bit application is treated as "intruder" and the user is asked to resolve the device conflict. Explanation: 6. Under Windows 95, whenever a 16 bit application protected by Sentry Hardware lock runs, the ‘device conflict’ window pops up. Ok Satus : Win NT/2000 Platform : In such a case log in as a user who has Administrative Rights and invoke install program again. Make sure that you have sentry.sys in the current working directory. Resolution: Under Win NT, system drivers are to be installed by user having administrative rights. The install program supplied installs Sentry.sys to the system. If the user does not have administrative rights, the installation of Sentry.sys fails. Explanation: 5. Cannot install Sentry.sys under Win NT/2000. DOS/DOS Extendor/ Windows 3.XX, Win 95/98/NT/2000 Platform : In such cases, it is recommended that the printer be kept Power-ON while lock access is made. Resolution: Some printers draw excessive power from the parallel port in their power-off condition. This leads to lowering of the voltage level below 2.0 V, inducing the Sentry to stop operating. Some PC's printer port does not provide pull-up resistors to driver signals, which also leads to the above condition. Explanation: 4. The Sentry is not getting detected when a printer is attached and is switched off. DOS, Win NT/2000 Platform : Microsoft acknowledged this problem, especially related to parallel port devices like hardware lock and corrected NTVDM in Service Pack 3. Upgrade Windows NT 4.0 with Service Pack 3 or better. Resolution: Win NT do not allows direct access to any system resources like IO ports, unless it is routed through valid NT system driver. Explanation: 3. MSDOS based 16bit applications protected with Sentry do not work on Windows NT 4.0. Ok Satus : DOS/DOS Extendor/ Windows 3.XX, Win 95/98/NT/2000 Platform : Use a new release of multitasking VxD, released in Nov 1999. Under Win32 systems, the Vxd supplied with Sentry hardware lock will not acquire the printer port if in use by some other process. Explanation: 2. Sentry is not accessed when a print job is fired on Win 95/98(win 32 application) Under Observation DOS/DOS Extendor/ Windows 3.XX, Win 95/98/NT/2000 Satus : Platform : This problem can also be overcome by fitting another printer port card. Sometimes, changing the printer port settings in the BIOS SET UP may solve this problem. There is a possibility that the problem may be solved by just changing the printer port type to EPP, ECP, SPP from the currently selected type. We further suggest you try every setting of the printer port (ECP, EPP, SPP, Bi-directional... depending upon the list available in BIOS setup) Confirm this by trying to check the lock (protected application) on different PCs. Also run the lock diagnostic program suitable for the operating system. If the error reported by the program is "Lock not installed" refer the following: Resolution: The hardware design of Sentry hardware locks is compliant to IEEE-1284 standards, however in some occasions, the PCs on which the lock is to be fitted may not conform to IEEE 1284 standards. Explanation: 1. On certain PCs Sentry locks do not get recognized. Support for Sentry Hardware Lock Resolution:
