DOCUMENT:Q121543 05-JUN-2002 [winnt] TITLE :Setting Up for Remote Debugging PRODUCT :Microsoft Windows NT PROD/VER::3.1,3.5,3.51 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server versions 3.1, 3.5, 3.51 - Microsoft Windows NT Workstation versions 3.1, 3.5, 3.51 - Microsoft Windows NT Advanced Server ------------------------------------------------------------------------------- SUMMARY ======= This article outlines how to set up for remote debugging. MORE INFORMATION ================ To set up to remotely debug another computer, do the following: - Remove the System, Hidden, & ReadOnly attributes of the BOOT.INI file and append the following strings to the boot line: /BAUDRATE=9600 /DEBUGPORT=COM# For example: [operating systems] multi(0)...partition(1)\NT="WinNT/S Ver:3.5" /DEBUGPORT=COM1 /BAUDRATE=9600 - Run Terminal against the above Com Port with the debug modem attached and enter the modem commands which set the following: Function USRobotics ------------------------------------------------- Set back to Factory Defaults: AT&F Disable Transmit Data Flow Control: AT&H0 Disable Receive Data Flow Control: AT&I0 Disable Data Compression: AT&K0 Disable Error Control: AT&M0 Auto Answer On: ATS0=1 Disable Reset Modem on loss of DTR: AT&D0 Write to NVRAM: AT&W - Determine the base build of the remote computer (using WinMSD, WinVer), 511, 528, 807 and copy the corresponding debug files from the base build: \Support\Debug\\*.* files to a \ directory and the corresponding Kernel & Hal *.DBG files from \Support\Debug\\Symbols\EXE and \Support\Debug\\Symbols\DLL respectively. For example: XCOPY E:\Support\Debug\i386\*.* C:\WinNT\Debug XCOPY E:\Support\Debug\i386\Symbols\EXE\NTKRNLMP.DBG ... ... C:\WinNT\Debug\Symbols\EXE /s /e XCOPY E:\Support\Debug\i386\Symbols\EXE\NTOSKRNL.DBG ... ... C:\WinNT\Debug\Symbols\EXE /s /e XCOPY E:\Support\Debug\i386\Symbols\DLL\HAL*.* ... ... C:\WinNT\Debug\Symbols\DLL /s /e where drive E: is the CD-ROM drive. NOTE: Using different (debugger 807 <-> target 528) kernel debuggers may prevent debuggers from "Sync"-ing. - Determine the Service Pack (SP) version (using WinMSD, WinVer), SP1, SP2, SP2b and copy the SP Symbols tree to the directory. For more information on the SP Symbols tree, contact Microsoft Product Support Services (Enterprise Technical Support). For example: XCOPY C:\WinNT\Debug\Symbols /s /e - Determine what Hotfixes, if any, have been installed, Prb18756, Bug18756 and copy the Hotfix Symbols tree to \. For more information on the Hotfix Symbols tree, contact Microsoft Product Support Services (Enterprise Technical Support). For example: XCOPY http://hotfix - Determine if you are using the Microsoft or third-party MP Kernel. If it is Microsoft's MP Kernel, then from \EXE, copy NTKRNLMP.DBG to NTOSKRNL.DBG. If it is a third-party MP Kernel, obtain a copy of the symbols and copy it into your \EXE\NTOSKRNL.DBG. - Determine if you are using the Microsoft Windows NT HAL or a third-party HAL. If it is a Microsoft Windows NT HAL, but not the standard ISA/EISA HAL, then from \DLL, copy the appropriate HAL*.DBG to HAL.DBG. If it is a third-party HAL, obtain a copy of the symbols and copy it into your \DLL\HAL.DBG. - Connect the modem to the remote debug target computer using the port from above and reboot the target computer. - Go to the directory and run the following REMDBG.BAT file: REM Modem String to Disable Flow Control and Compression ECHO "UsRobotics Modem string = AT&H0&I0&K0&M0" REM Environment Variables: REM Specify which com port to use. (Default = com1) set _NT_DEBUG_PORT=com1 REM Specify symbol image path. (Default = x: * NO trailing backslash *) set _NT_SYMBOL_PATH=%2\Symbols REM Specify second symbol image path to be searched after the above. set _NT_ALT_SYMBOL_PATH=%3\Symbols REM Specify the baud rate used by debugging serial port. (Default = 19200) set _NT_DEBUG_BAUD_RATE=9600 REM If specified, output will be APPENDed to this file. set _NT_DEBUG_LOG_FILE_APPEND=DEBUG.LOG REM If specified, output will be written to this file from offset 0. REM set _NT_DEBUG_LOG_FILE_OPEN=U:\WinNT\DEBUG\DEBUG.LOG REM set _NT_DEBUG_CACHE_SIZE=x remote /s "%1kd -m %4 %5 %6 %7 %8 %9" debug REM Usage: *kd [-?] [-v] [-m] [-r] [-n] [-b] [-x] [[-l SymbolFile] [KrnlName] REM where: REM -v Verbose mode REM -? Display this help REM -n No Lazy symbol loading REM -m Use modem controls REM -b Break into kernel REM -c Resync on Connect REM Control Keys: REM . Break into kernel REM Quit debugger REM . Resynchronize target and host REM . Toggle Verbose mode REM .
